Website news for November 2011

This is the first official website news for Iceland volcano and earthquake blog for November 2011. The purpose of this web site news is to tell people what is going on with me [Jón Frímann] and this web site that I run. I do not intend this to be a long blog posts unless I have to. This is going to be divide into needed sections of what is going on. I hope that have this every month from now on.

Monitoring changes for earthquakes and volcanoes

The following areas has been added to my personal monitoring system, Spain and Canary Island (part of Spain), Denmark (since February). Following areas are now part of special report system. Azores Islands, Madeira Island. But special reports cover eruptions and major earthquakes for a short time period. I also cover all major earthquakes that happen on the planet Earth. That is earthquakes that are larger then Mw8.0 in size. I have to have limit to what I cover here. As I cannot have good quality if I am cover too much. I rather want to cover less and have better quality of what I cover.

Twitter

I have added a twitter button to this web site. So links can now be shared more easy on twitter. Facebook button is so far not in the picture. As they are just too complex to setup from my point of view (they also appear to track people from what I can gather). So I won’t bother with setting up a Facebook button.

Web site traffic

It took one year to get 1 million page views. But it only took a month or so to get up to 2 million page views. Currently the page load counters stands in this number, 2,142,929 page loads. But this equals to 652,725 visits to this blog during a little bit over the year. For the earthquake pages there have been 3,057,298 page loads since that web site was started back in the year 2006. But that are 696,378 visits to that web sites since I did start it. So far the traffic does not warrant a move to dedicated server. But that might change if the traffic grows even more in the future. So I am watching out for that possibility in the future.

Geophone network

The geophones that I did order are finally in Iceland. I am going to pick them up at the post office tomorrow I hope. I hope that I can install and start both of them in December. But I am not going to have time to install then in November.

Money issues

I became debt free yesterday (finally). The last day of October 2011. But that does not change the fact that I am going to continue to be broke as I have been. Since now I have to spend my money into saving for the move to Denmark (since I was unable to have both options). I am also saving up so that I can buy a new tv, as my old tv is getting tired and bit breaking down in the tube monitor (I also find it better to look at LCD monitors, but I have poor eyesight). The total cost of moving back to Denmark and buying a new tv is estimated about 4.396,00€, 32.697,00DKK, 6.153,00$, 3.843,00GBP, but this is about 700.000 ISK that I need to save up before I can move back to Denmark. But I am saving everywhere that I can. I have placed payments from Google Adsense on hold so I can save that money. I am not getting anything from Amazon ads at this moment, so it does not matter at current time. The saving for the move to Denmark starts tomorrow. It is going to take me until June to get the money that I need to move back to Denmark. I plan to start looking for a apartment in March or maybe earlier. It is a bit unclear at the moment. But it is going to take few months to get apartment in Denmark (I think). But I am in a hurry to move from Iceland for many different reasons.

Update 1: Due to currency restrictions in Iceland I cannot save money on Google Adsense as I had hoped. As I am going to need that income to pay for bills and other things from my danish bank account. I just hope for the best in this regards.

For that reason I am going to have to relay on donations as before. At least until this annoying period in my life goes over. I do not ask for a lot. Just something to make the month in terms of expense that we all have to deal with.

Thanks for reading and the support.

  1. If you really want to run a business or passion about volcanos, you could start with a simple “thank you” to those who have made a simple donation to you 😉

    1. Thank you web page is in the work when I have time. But that should be soon.

      But there is a thank you on the bottom of this article as always when I cover donations to me.

  2. “It took one year to get 1 million page views. But it only took a month or so to get up to 2 million page views. ”

    Congratulations Jon. That is a hork of an achievement although of course we should say a thank you to Iceland and her volcanoes for being so utterly fascinating and breathtakingly beautiful. I think the Icelandic Tourist Board and even the IMO owe you a debt of gratitude (hint hint). If I had the money I’d be there in a heartbeat – although this may only be because I want to dance naked in front of the Katla cam and see the dreaded sheep 😉

    Having surfed the web since the 90’s I have to say this is a place I would gladly call home! It is a wonderful community you have built up and thanks must also go to them for being so welcoming to newbies. Your site is what the web was built for – the exchange of ideas. Without you it wouldn’t exist, so thank you. I’ve loved reading everyday for several months now. I’m glad you’re expanding as it means I don’t have to go anywhere else now, you’re becoming a hypermarket on the web for all things seismic 🙂

    Best of luck with the move/saving. I’ll gladly contribute as/when I can.

  3. Congratulations from me too. I go along with Craig on almost all points. The internet really comes into its own here. I have very much admired your initiative and determination, Jón.

    However, for me, and I’m being totally subjective here (is one allowed to be on this blog?), it is partly the focus on Iceland that I come for. I’ve been fascinated by it since my teens and have been a volcano-watcher since my visit in 1979. El Hierro is important and extremely absorbing, but time doesn’t permit me to travel everywhere, even from my armchair. It is a tad discouraging to have to trawl through all the discussion of the Canaries for commentary on Iceland (I’m particularly concerned with what’s been going on recently at Hengill). I understand the diversification, but wonder whether there is a possibility of a constant thread that can be visited for Iceland updates and commentary.

    Thanks, again, though to you, Jón, and the fantastic people who have joined the discussions.

    PS Diana: as an English ex-pat of over 25 years, I enjoy a twinge of nostalgia for the Pennines. Get well soon!

    PPS You guys may not realise that here on the Baltic coast of Poland we had quite a rattler (5.2) on 21st September 2004, when Scandinavia bounced up unexpectedly.

    1. @On the fringe
      Many thanks for your kind thoughts. I am now recovering well and it wont be long before I am digging my vegetable patch again. I don’t think I am quite up to walking the Pennine Way……yet! 🙂

    2. Jon – The simple solution to ‘on the fringe’ comment above would be to have a page for iceland events and monitoring, and a seperate one for the Canaries.

    3. Good idea!
      I think you pointed out something that will become increasingly more important as Jón expands his Blog. That the discussions get to spread out. I think we will sooner or later need to have two open threads and that we (the commentors) try to keap to the apropriate thread.

      1. I think that, too.

        Especially as the Canary Islands thread, which in the beginning was perhaps thought to become very short, could develop into a “long-runner”.

  4. Hey , Jon, that’s really super! Debt-free!! Of course live isn’t suddenly easy but it is good to have plans and visions. One day at a time, you’re getting there.

  5. Debt free, congrats!

    Can’t say the same for meself though… Currently 2.456.000.- Norwegian kroners in the red (31.861 Euros)!

    So give me another 20 years and I’m debt free too! 😉

      1. Missed a digit! Yep it’s a house mortage so no stress really ^^ Or at least it isn’t as long as the housing prices keeps rising the way they are 😛

      2. I don’t really count a morgage as a debt, since you have substance value that is (if one live in Scandinavia) that is higher than the morgage. 🙂
        Personal debts are much worse, they cripple people since they do not have the offset of any value for the debt.

      3. Tell me about it:) Like you I keep going off on harebrained schemes (companies) that do not always pay/ fulfil thier promise and am paying the price for my poorer judgements. Ouch.

      4. Housing prices crash periodically, so mortgage will turn into pure debt for those who were first time buyers at a bad time. It might be better to look at the insurance value rather than the market value to determine your risks. I think it’s different in the US, though, where people can walk away from the mortgage by letting the bank have the house.

        I wouldn’t recommend anyone highly dependent on a mortgage to be a first time buyer in Norway at the moment.

      5. JulesP, if you too are into companies then you know the fact that when we hork up, then it is cluster-horkup that happens.
        I hav learnt to always keap 1/3 of the money safe at all cost. And then to divide the rest over many projects. I basically learnt it once by loosing everything, and then I mean exactly everything.

  6. Hi Jon congratulations, another milestone reached.
    You do well to plan and have goals in life. Even if something happens to change your direction as often happens, planning gives something to aim for.
    Jon, you have overcome so many difficulties and have shown what can be achieved with determination and bravery.
    It is a special sort of bravery to set out to start something when odds are against you and maybe those around you think you are not capable. Jon, you are an inspiration to many more people than you realise.
    Along with the posts above I send my thanks for hours of interest, information, friendly banter, Icelandic beauties and of course …the fun with sheep!
    The usual small Donation coming at the end of the month 🙂

  7. Buenos dias amigos. Takeshi Sagiya, colabora con el INVOLCAN, y con el ITER, y con Nemesio Perez que es el director del Instituto de Energias Renovable. Creo que son las personas que en este momento saben mas de Geologia y de Volcanologia en Canarias.

    1. ¿Podría explicar un poco lo que los enlaces están a punto. Los comentarios con enlaces que ninguna explicación no es bueno, ya que no decirle a la gente lo que está en ellos. Gracias!

      (Google Translate)

      1. Karmela:
        Si usted no desea escribir en Inglés, escribir los comentarios en español, muchos aquí se puede traducir y entender los comentarios en Inglés para usted.

        Basically I wrote that we would help her to translate comments into english. This since Karmela is really good at digging out interesting articles about El Hierro that I often never find at other places. Worth the while even if we have to giggle it.

      2. Her links don’t scare me. or bother me. Its the one that say “Hey sounds like a good blah de blah” and then stick some carp out there that really tick me off.

        On the other hand Her data is good… even if its a bit brief in description.

      3. Lo siento mucho, les pìdo excusas por ser una usuaria novata, y ademas hablar solo español, Me parece que para aprender otros idiomas no sera facil, pues me siento mas vieja que la isla del Hierro…..

    1. Not only 5-6 Hz, but the entire frequency range… The eruption is definitely intensifying right now. Will it surface and where?

      1. Yes – even the lower frequencies in the ‘red zone’ have intesnified – perhaps something is already underway

      2. I would guess that this is “cavitation” as the steam is starting to create bubbles. It is of course not real cavitation, it is steam explosions. It think the increase in tremoring is either Bob of La Restinga that is picking up eruptive power, or Bob getting so close to the surface that the eruptive behavious is starting to get explosive. If it is the latter we should start to see an Island formation within a week or two. Unless it closes up before that.

        It is also telltale that local deflation has picked up speed lately, I therefore guess that the eruption has increased in speed. I still stand by my forecast that Bob can erupt yet another 0,1 – 0,4 cubic kilometre of ejecta in addition to the already ejected 0,1km^3.

        Odd that little Baby Bob has ejected equaly to Eyjafjallajökull without making much noise about himself. But the pictures of the ocean floor combined with admiralty charts (and a spanish chart) gave me a good ground to calculate the actual volume of ejecta. Baby Bob have grown up into El Bob of la Restinga now.

      3. I am not really much into geology, Carl. Could you perhaps explain what you mean by “cavitation” (the volcano emerging out of the sea, perhaps)?

      4. Cavitation is the formation of bubbles from the gasses that are in water. One of them being … water.

        Usually seen in the high-speed interaction of a screw (propeller) and a boat, the extreme low pressure of the propellers aerofoil allows some of the disolved gases to come out of solution, and for some water molecules to enter a vaporous state. Though not strictly “boiling,” it has to d with modifying the equilibrium state and having bubbles form.

        In a submarine, you try to avoid it since it gives away your position from the noise.

        In this sense, Carl means it’s starting to make bubbles. Pretty good too from the looks of the graphs. These “bubbles” would be gases in the magma coming out of solution.

      5. @Lurking, in part I meant the gasses coming out, but I mostly meant the steam explosions that I think happen now as the water pressure has decreased as the volcano has gotten higher.

        A high volcano? Cheech & Chong perhaps would have been better names than Bob…

  8. New blog post about El Hierro is planned for today. Along with pictures from space (modis), if I can find them.

    I am not going to setup special blog for the Canary Islands and Spain. Doing so is too much work.

    1. Might though be a good idea to have to active threads, one icelandic and one spannish. And then trying to softly pushing us into using the appropriate thread. I think that would work fine, after a bit of a period of getting used to rambling in the correct thread.

    2. Hi Jon,
      latest MODIS pictures are published in “real time” here on the Rapid Response website, but you need to wait until the afternoon, because the satellites (Aqua and Terra) pass the Canaries usually between noon and 14h every day:
      http://lance-modis.eosdis.nasa.gov/cgi-bin/imagery/realtime.cgi
      You can check the orbital tracks for each of the satellites to see the time when they pass over Canaries, then it takes some 2-3hrs for the pictures to appear.
      Hope this helps.

    3. You dont need a special of seperate blog Jon, just a seperate page within this blog. Home page could become @Iceland Volcanoes and you could create another page for posts and reports for Canaries volcanoes. As Carl has said, we then just need to be disciplined about which thread we post to to make sure that comments on El Hiero etc are made only on the Canaries page etc.

      1. Sorry that was meant to be a reply to the comment some way up the page – dont know what happened there!

  9. Well done, Jon. Being clean in matters of money is a very important thing – but for sure not always easy…
    And like others I’m convinced that you offer exactly what the internet was thought for: exchanging ideas in a free way all across the globe. Personally I love to see that there are many “loco” people living on the blue ball… Haaaahaaaaa (really faaat laughing)!

  10. http://www.youtube.com/watch?v=AEn_54Uwl80
    Comment from the Youtubeclip
    “Thanks Christianna.
    Things could get very interesting this month. An alignment due involving the planets Mercury, Venus, Earth and the commet Elinin on the 3rd.
    Look out for something on 11.11.2011.
    I have also scribbled down something for the 23rd November, “3rd and final conjunction” related to Elenin, solar activity or both.”

    Something we should care about?

      1. And I’m so short, because we’ve had this discussion many times over that:
        – planets and their alignments don’t affect volcanos/earthquakes
        – moon doesn’t affect volcanos/earthquakes
        – solar activity doesn’t affect volcanos/earhtquakes.
        There is no proof for any of these and on this blog we stick to proper scientifically-proven discussions/guesses. You may want to dig through old posts, if you are interested in any of the above to see that there is no linkage whatsoever.

      2. Thanks for the answer. Dig trough old post are almost impossible now when its a hell of a load of them. =)

      3. Comet Elenini was a real comet, that’s a fact even though the 2012-dorks stole the story.

    1. Actually there is no comet Elenin anymore, it disintegrated into dust due to solar heat.

      1. Wasn’t Elenin that brown Dwarf that was suposed to be hiding behind Jupiter together with a UFO? I have a problem reminding those things for some reason…

  11. Great stuff, Jon!

    I’m so glad you were able to keep this blog going when things were so difficult financially, and thanks from me, too, to all those who were able to contribute to keeping it going.

    Back to El Hierro –

    Carl and Peter
    The concept of plates pushing south ties in with my sense of the cooler magma being pushed south, extruding more slowly from the more sheer slope on the south coast of El Hierro. This is forming Bob and may be pressuring release of gases from other sources along the south coast.

    The rifting is east-west concurrent with the north-south pressuring.

    The rifting therefore meets the ridging, leading to cracking under El Golfo where the rifting meets the bulk of El Hierro, which is embedded in the crust if this is correct, thank you Peter.

    It then pressures the magma already under El Hierro, but the weight of the island suggests extrusion rather than intrusion on the south, in contrast to direct infusion from the mantle under El Golfo where there is a risk of a very large eruption in my view. The magma is moving steadily up towards the surface, at this location, and although some experts hope it will stop before it reaches the surface, deformation is now evident and gases and heat are rising too in El Golfo. I wish they would evacuate sooner rather than later.

  12. Juan Santana responds:

    “We have not hidden anything because a population who knows what will happen is better prepared”
    “I have has ejado very pleasantly surprised by the civility of the population of El Hierro. In all the speeches that we have had, I was surprised, I was excited and I am happy as Canary, see the civility of its inhabitants and how they have faced and face this process “.
    “The eviction of residents of the Restinga, although difficult, was a wise decision.”

  13. A new tremor pattern is emerging at Vogsosar looks very much like that at Askja for about month after the Grimsfjall eruption, before it settled. What could be causing this? Could this be subterraenean magma flow we are seeing?

    1. I was looking at this a few days ago Jules, and the verdict was just the weather. However, it’s stayed around long past the storm now, and other coastal sites in the area aren’t affected, so it’s not wave activity. Rather that the Askja plot, it looks much more similar to me to the Vestari Saudahnjukur plot, which has gone through exactly the same sort of transition a couple of months back. That, I believe, is thought to be due to a nearby hydrothermal project, which presumably became more active around that time.

      The Vogosar signal doesn’t look how I’d expect magma movement to appear – no spikiness, just increased noise. I was wondering at some hydrothermal activity instead, but there’s nothing showing at Krisuvik, where you’d expect to see that (assuming it’s not some new and completely localised system). Of course, it could be that one of the locals has bought a new music system..!

      Interested to see people’s thoughts on this. After all, I know nothing! 🙂

      1. Re Askja – multiple SILs showed tremor plots like this around the time fo the Grimsfjall eruption. Askja was unusual in that it maintained this pattern for some weeks after all other stations had resumed their normal pattern; it took some months to settle back to its current state. I was not suggesting it was ‘like’ this now; rather that it was very like this in the recent past after Grimsfjall.

        I have dug into research papers and everything I could find to try and find some explanation for this sort of behaviour, but have not been successful – but as a rank amateur, I am probably looking in the wrong places!

      2. OK, I’m misremembering Askja, then – I thought it was much more erratic rather than “only” noisy.

        I remember someone pointing out once that a glacier flood signal could look like this, but surface water flow it doesn’t seem entirely satisfying – even if there had been very heavy rain there recently, why nothing on the other SILs? Sounds like you’ve put more effort into this than I have, anyhow.

  14. El volcán submarino de El Hierro ha vuelto a expulsar este lunes piroclastos (fragmentos de magma) humeantes a la superficie del mar, frente a la costa de La Restinga, según han confirmado a Efe fuentes del Gobierno de Canarias.
    Además, esta vez se ha apreciado que los fragmentos de magma que emergen desde el volcán son de mayor tamaño que entonces y provocan una coloración más oscura en el agua. Segun dijeron ayer Lunes, parece que nuestro Bob el Pedorro se ha hundido, y que es posible que una nueva boca se haya abierto en la misma fisura pero mas cerca de la costa de la Restinga.

    1. Giggle translation made my day:

      The submarine volcano has returned to El Hierro Monday eject pyroclasts (fragments of magma) steaming the sea surface off the coast of La Restinga, as confirmed to Efe Canary Islands Government.
      In addition, this time it has found that magma fragments emerging from the volcano are larger then and cause a darker color in the water. According to yesterday said Monday, it seems that our Goldfarter Bob has sunk, and it is possible that a new mouth was opened in the same crack but closer to the coast of La Restinga.

      1. I tried Giggling it using Catalan instead of Spanish to see if the translation made better sense, but it was equally chucklesome- they’re opening crack houses in Restinga!

  15. El Hierro underwater volcano has returned to expel smoking pyroclastic (fragments of magma) to the surface of the sea, off the coast of La Restinga, as they have confirmed to Efe sources of the Government of the Canary Islands.
    In addition, this time it appears that the fragments of magma that emerge from the volcano are larger than before and cause a darker stain in the water. They said on Monday. It seems that our Bob Farter has sunk, and that it is possible that a new mouth has opened in the same rift but nearer to the coast of la Restinga.

  16. Los ultimos sismos de 3.9 se han sentido en Valverde y en Frontera mas fuertes que nunca. Nemesio Perez se esta “partiendo el alma” en estrecha colaboracion con el cientifico japones Sagiya, para poder predecir por donde seria probable la nueva erupcion, y obtienen datos con camaras termicas desde el Cuco, Helicoptero de la Guardia Civil, para confirmar imagenes termicas de volcanes y grietas en el Julan y el Tanganasoga. Sorry, ( me he propuesto aprender ingles) .

    1. The latest EQ of 3.9 have been felt in Valverde and frontera stronger than ever. Nemesio Perez is colaborating with the Japanees scientist Sagiya to predict where the new eruption would probably be, and they’re gatherin data with thermal imaging cameras from the Cuckoo, the helicopter of the Guardia Civil, to confirm thermal images from volcanos in el Julian and Tanganosa. (sorry, I have decided to learn english).

      1. “”..to confirm thermal images from el JUlan and Tanaganosa….”
        That suggests hot gases at surface already? Anyone been up there?

      2. There was a comment about that a couple of days ago, if I remember well an aircraft had made thermal images of Tanganasoga.

  17. Congratulations, Jón! 🙂
    Monthly donation underway.
    Only hoped I had time to participate of the discussion more often.
    But you know, as year comes to an end, teachers have almost no time.

    From Karmela, above:
    “New smoking pyroclasts, bigger than the former ones, seem to have reached the surface at La Restinga shore.
    According to what has been said yesterday, it is possible that a new vent has opened in the very same fissure, but closer to the shore of LA Restinga.”

  18. Important Update 01/11 – 11:24 UTC
    A new El Golfo Helicopter video has been published on you tube. The quality is poor but it looks like a ‘green stain’ eruption has started in the El Golfo bay. More video will have to be conclusive, but as it coincides with the stronger harmonic tremor, it can certainly not be excluded.
    We remind our readers that also in the La Restinga / Las Calmas eruption, it started with a green stain only eruption, later followed by the Jacuzzi / Burbuja and thereafter by the grey muddy like stain.
    Decisive information will soon come from IGN or CSIS we reckon.
    More:

    [link to earthquake-report.com]

      1. Or looking for some one. SAR in this case means Search and Rescue, not Synthetic Aperture Radar.

  19. Congratulations!!.
    I’m debt free.. and with job in Spain..
    a really rare status here this days.

    http://www.youtube.com/watch?v=h5AW3lbFO5M

    Post this video in old theme.. and repeat here.
    User don’t know if is a new ‘plume’ or rest of old one from La Restinga.
    From coast say that old one is more transparent, less green.
    can be a new one?

    People in coast has start to smell ‘putrefacted eggs’.. and ‘acetona’

    1. In the last second of the video we see the headland east of Frontera, where the tunnel is. So that puts the stain above the present deep EQs. That does not mean magma is coming from greta depth. Indeed the stain may be hot suphurous gas released by the many shallower EQs in July/August under that same site.

      1. The sharply defined northern edge to the stain suggest to me its not old stain that has travelled from Restinga. I think its new.

  20. @ Jack.

    Goldfarter Bob. Now that was hilarious. 😀
    Thats the official name of the new volcano?

    “Gullvindgangur Bob”

    1. I think we all love it, and since Karmela is from the island I think we should keap that name.
      Question is just, is GoldfarterBob the new Bob or the old Bob? 🙂

  21. Good work Jón and congratulations 🙂

    I will contribute more € for your exceptional good work on this site, thank you!
    This site is my startpage since July -11 🙂

    OT: I believe ol’Ejyafalla have started smoking again, this time higher up in the area where I think, the main eruption was located. A convective cloud has been lurking there for a couple of hours now at the same place…

    Cheers
    Christian T. (SWE)

      1. Actually the volcano’s name is the same as the glacier’s: Eyjafjallajökull. To have a (easier to pronounce) nick name, we could also call him “Eyja” (as do the volcanologists sometimes, from Earth Sciences Institute, University of Iceland). Eyjafjalla is an inflected form, because Icelanders use the genetive to build composita (composed words).

        eyja = island
        fjöll = mountains (pl.), gen. fjalla
        jökull = glacier

        Eyja-fjalla-jökull
        (glacier of the island mountains – it’s just opposite of the Westman islands)

  22. Here is a good reason why I do not want to live in Iceland.

    I am trying to transfer money to my danish bank account to pay the phone bill that I continue to have in Denmark. As I did not want to loose my danish phone number, as I was only planning on living short term in Iceland.

    But now I cannot. Due to #$% currency restrictions that are in Iceland. So I cannot exchange ISK to DKK without proof that I am actually paying the bill.

    Iceland have great landscape, volcanoes and earthquakes. But rubbish economic policy. For that second reason, I am out and not going back. As last 50+ years have not been good in that terms for Icelanders.

    1. Jón, you might tell people from other EUROPEAN (EEA) countries to temporary donate directly to your Danish account. It is easy, free and fast (as it should be from Iceland too!).
      So folks, if Jón wants to, you can easily transfer your donation by online banking, you only need to fill in his Danish IBAN and BIC / SWIFT numbers which are on his donation page.

  23. En una entrevista publicada hoy, al director del Servicio de Emergencias del Hierro, Juan Antonio Santana, en relacion a lo que puede durar esta crisis volcanica, contesto:
    “Uf, esa es la pregunta del millón (risas). No lo sabemos. Va a depender de la emisión de magma. Los científicos nos decían que, en función del cálculo que ha realizado de la emisión de magma que se ha producido para la conformación del edificio volcánico, calculaban del orden de 24 millones de metros cúbicos de lava que se han emitido ya. Pero la duración no lo sabemos. Se baraja desde un mes a un año, en base a los cálculos de los científicos, aunque es muy difícil aventurar nada”.

    1. Google translation on Karmelas post:

      “Ugh, that’s the million dollar question (laughs). We do not know. It will depend on the emission of magma. Scientists tell us that, depending on the calculation that has made the issue of magma that has occurred for the formation of the volcano, estimated around 24 million cubic meters of lava that have been issued already.

      For the Dutch folks, to have a good lauch at Google Translate, “Servicio de Emergencias del Hierro” is actually translated as “Emergency Services Strijkijzer”

      1. Lol! Strijkijzer is to iron clothes with, es ‘plancha’ (para ropa) en español…

        Oye Karmela, no te preocupas por escribir en español, algunos aqui podemos traducir, y el resto ya se está acostumbrando a utilizar e interpretar la lengua oraculosa del Google traductor – que llamamos “Giggle Translate” porque da risillas. Pero me parto por lo de “Follafolla” de ti madre para llamar a Eyjafjallajökull 😀

      2. I am amazed at how much they miscalculated the ejected volume of Goldfarter Bob. They only missed the goal with a whopping 300 percent. Do they know how to calculate volume shifts at all???

  24. Y yo me pregunto; El pequeñajo Bob, alias el Pedorro, como puede haber expulsado tanto material magmatico, y en vez de crecer como un gigante, se ha encogido como un Pitufo??? Esta pregunta, y muchas otras mas, se van a quedar sin respuestas, porque los medios que tenemos para llegar hasta la Cueva de Bob, no son sufientemente modernos ni especializados. Yo creo firmemnte que el famoso “torpedo perdido” esta tratando de salir por el Golfo……..

    1. JAJAJA…
      La respuesta está en la pendiente sobre la que ha crecido.
      Si creciese en un llano, habría aumentado mas de altura.. pero tiene que rellenar muchos metros de pendiente, de barranco oceanico.
      24.000.000m3 me parece una cantidad grande, pero es lo que se le calculaba para 700m de base, 120m de crater y 100m de altura en un barranco (teniendo que llenar el barranco)

      http://www.ieo.es/images/hierro-antes-despues.jpg

      1. Giggletrans:
        “”The answer lies in the slope on which it has grown.
        If you grew up in a plain, would have increased more in height .. but you have to fill many meters of slope, oceanic ravine.
        24.000.000m3 I think a large amount, but that’s what you base calculated for 700m, 120m and 100m of altitude crater in a ravine (having to fill the ravine)””

    2. Amateur non-google translation:
      And I ask myself, The tiny Bob, aka the Goldfarter :-), how could he have expelled all this magmatic material and instead of growing into a giant, has shrunk as un Pitufo (??? Smurf?). This question and many others are going to remain without answers, because the means that we have to reach Bob’s Vave, are not sufficiently modern nor sufficiently specialised. I firmly believe that the famous “lost torpedo” (???) is getting ready to enter el Golfo…

      1. HAHAHA…

        The answer is in the slope of the area where Bob appeared.
        If it appeared on a plane surface, it would have grown more in height .. but now it has to fill in the steep and deep oceanic valley.
        24.000.000m3 seems like a large amount to me, but that is calculated for 700m width at the base, 120m width of crater and 100m to fill in the valley (having to fill in the valley).

      2. Last time i calculated a 15.000.000 m3 emision to form a truncated cone with 700m base diameter , 120m top width diameter and 100m hight.

        but these ‘little bob’ volcano has grown in a deep valley.. And first had to fill that valley… so 15.M m3 was conservative.

      3. a ‘pitufo’ is an smurf
        “instead of growing into a giant, has shrunk as an smurf”

        “I firmly believe that the famous “lost torpedo” (???) is getting ready to enter el Golfo…”
        She talks about the seaglider lost 20-10-2011..
        Its a joke:
        The lost seaglider (the torpedo) try to open a new vent in El Golfo to return to surface..

      4. Did somebody actually loose the torpedo or did someone try to shoot the island?

        Way back when, while firing air slugs, one of our Gunners managed to shoot a car. Planted the torpedo right on to the pier and into the car. (he didn’t check all the tubes first)

  25. New ‘strong’ quake in El Hierro.. intensity unknow at the moment.
    La Restinga, El Monacal, Frontera…

  26. Segun noticias se ha detectado error de sismografos del IGN. Se ha comprobado que el epicentro de la erupcion de Bob, se localizo con un error de 6 kilometros y pico, en direccion Sur/este, alejado del enjambre sismico del Pinar. Si aplicamos este mismo margen de error en el enjambre sismico de Frontera en la misma direccion Sur/este, nos cae en tierra y sobre el mismo pueblo de Frontera. Espero haberme explicado bien.

    1. Giggletrans:
      “According to news seismographs detected the error of IGN. It has been shown that the epicenter of the eruption of Bob, is located with an error of 6 km and beak, south / east, away from the swarms of Pinar. If we apply that margin of error in the Border seismic swarm in the same direction south / east, we fell to the ground and in the same town of Frontera. I hope I explained well.”

      Yes it does look very symmetrical.

      1. – I was referring the new sea stain in El Golfo as being symmetrical with Restinga’s stain. And both stains have symmetry with the EQ swarms, the shallow ones from July to end Sept, and the larger ones (mag 3+) now in the north and in September to the south.

      2. Pico means “a bit more than…”, “just a bit over”… so “much more” is not correct.
        ~’vemonos a las tres y pico’, we meet at just after 3 o’clock; ‘un metro y pico’, just over a meter..
        Tien ser: ‘6km y pico’ dice 6km y ‘un poco más’, algo más que 6km…

  27. ADJUNTO DOS GRÁFICAS, UNA CON LOS EVENTOS SÍSMICOS DEL 11 AL 16 DE OCTUBRE, SUPUESTOS MOMENTOS DE LA ERUPCIÓN SUBMARINA Y OTRA DE ESTA MAÑANA, CON LOS ÚLTIMOS SISMOS DE MAYOR MAGNITUD.

    SI SUPONEMOS QUE HAY UN ERROR Y MOVEMOS EL ENJAMBRE DEL MOMENTO DE LA ERUPCIÓN UNOS 6,5 KM AL SUDESTE, LO HAREMOS COINCIDIR MÁS O MENOS CON LA ZONA DE SALIDA DE MATERIALES.

    SI HACEMOS LO MISMO CON LA GRÁFICA DEL DIA DE HOY, EL NUEVO ENJAMBRE NOS QUEDA CENTRADO EN LA ISLA EN LA ZONA DE CONFLUENCIA DE LOS TRES VÉRTICES DEL RIF Y JUSTO SOBRE FRONTERA…

    1. Thank you very much for the links.
      However, is there an explanation for what the red and green lines mean?

      Muchas gracias por los enlaces.
      ¿Pero existe un explicación sobre que significan las lineas rojos y verdes?

  28. As isch as bitzeli müesam wenn a jeda hie fet afa i sineri Muetersprach schriibe. Aber das muess natüerlich de Jon entscheide. Nume irgendwie wird’s haut kompliziert mit de internationaali Kommunikation.
    Gau nume? Oder net? Bruuch doch de Google tränsleiter, de spare wier üs das wenigschtens. Wäge vom iPhone uus jedesmau kopiere u wider inechlääbe schiisst as Stück wiit aa.
    🙂

    1. U we dier das nit ärnscht nämet, de schiiesseni Euch Watta a Rügge u houe ‘nech mit de Stromgittarra uf ds Füdle. So! 🙂

    2. I tried to understand, but you lost me after the first paragraph…
      And I don’t think google translate can do Swiss Deutsch yet, can it? 😉

      1. Naaaah, it can’t. Scandalous… 🙂
        Superb infos by Karmela, but it’s quite “annnnnoying” (don’t take it the bad way) to always transgiggle it when you’re on a mobile device. If Kammy could do it before posting, we would be many to save this step… But sure there’s a good reason why she doesn’t and it was explained before but I missed it as catching up several days on this blog has become impossible… 🙂
        To “release pressure” of my frustration because I’m not exactly fluent in spanish, I opened a vent by complaining in Schwyzer Dütsch (dialect of my region – we’re not many with exactly that, but yeah, well, whatever…). To my defense, germans ans austrians also have local specificities that easily compete with ours… 🙂
        Let’s all learn icelandic, the world will be a better one. Maybe. Always worth a try.

      2. I think the first means more or less:
        Its a little bit tiresome if everyone here writes in his mothers tongue. But this is up to Jon to decide. Still it gets somewhat complicated withthe international communication. ? More. or not. Use Google translator, then we dont need this part at least. Because to copy each time and upload it back from Iphone schiesst ein Stück ???????
        (((No idea about the dialect, just being a german native speaker here.))

      3. Goes on as:
        And if you dont take this as serious, then Watta a Rügge (???) will hit you with electric guitars on the ???. Yeah

      4. I love the attempt. 🙂
        Gau nume= gell/nicht wahr.
        Copy paste some kind of sucks… (schiisst as Stück wiit aa – scheisst ein Stück weit an)
        de schiiesseni Euch Watta a Rügge – then I shall throw cotton balls at your back (don’t think about it, just a stupid expression to say something and nothing)
        Füdle=ass, Stromgittarra – electric guitar, but sounds really weird when said the “right way”.
        Seen the kind efforts of my german friends, I would nearly begin to consider de EU if you guys were not that economically FUBAR… 🙂

      5. Sorry, iPhone fastwriting is a bad idea.
        I would nearly consider joining the EU if…
        Erm, forget it, let’s go volcano…

    3. Seems easy enough to understand – what’s the problem – not got a babelfish in your ear ?

      well some people can’t manage the english – so if they are posting useful links and can put some comment on them (for us to google translate) it’s better than no comment and just the bare link 🙂 and also better than not sharing the useful links. Especially for those of us what can (more or less) read whatever germanic based language that was, and also manage similar levels of spanish.

      Edward 🙂

      1. Absolutely right. No doubt.
        Schwyzerdütsch comments clearly to see as “friendly banter”, please.

      2. Now we just need a slavic language into the mix…
        …in potem se zabava lahko zacne. 😀

    4. Und Du bist Dir nicht ganz sicher, ob Switzerdütsch im Google translater ist?
      (And you are not really sure if Swiss-German is in Google translater?)

    1. No. Eyjafjallajökull volcano has gone back to dormancy for now it seems. Currently it is rated as level 2 volcano in terms of activity (my own system once again). With downgrading to level 1 from 1 February 2012.

      1. Its better to see now. Its just a cloud which casts a shadow on itself. The sun is standing pretty low in Iceland already, so you have to take this into account as well.

  29. @Peter, Carl, Jack.

    Near the end of the last thread, there is a link to a paper dealing with the formation of La Palma and El Hierro.

    Essentially, the paper states that these two islands may represent a mode change in the mode of the Canary hotspot.

    Gomera being the last “single island generation” event and it now has adopted driving two near simultaneous volcanic regions much like Hawaii does with the Kilauea/Mauna Loa pair. In this case, La Palma and El Hierro alternating back and forth over time through the active/dormant periods.

    To me this poses a question.

    For about 500 years or so, most of the activity has been on La Palma with little activity at El Hierro. Could we be seeing a transition to El Hierro focused activity?

    http://acceda.ulpgc.es/bitstream/10553/383/1/1463.pdf

    Also… I placed a graphic over there that shows a profile view looking east of El Hierro and all pre-2011 quakes in the IGN list. (well, those that have a depth value).

    As you can see, there was activity below now active lower set over the years.

    http://i41.tinypic.com/a3dwro.png

      1. Giggeltrans:
        “”The PhD in Geological Sciences from the Universidad Complutense de Madrid and Research Professor of the Higher Council for Scientific Research (CSIC), Juan Carlos Carracedo, said Friday in La Palma, “it’s delaying the eruption, which, statistically, it corresponds to the island. ”

        Carracedo, the presentation of his book Geology of the Canary Islands, held at the headquarters of the National University of Distance Education (UNED) in Santa Cruz de La Palma, said that while “nature does not have the same rhythm human beings, “according to the historical average in La Palma has one of those episodes every 35 or 40 years. However, he said that at some period, have also been more than 300 years.

        The effect explained that La Palma and El Hierro, according to a process that is still under investigation, called on-off model (on-pay), “form for the first time in the geological history of the archipelago double alignment.”

        This means that, while Fuerteventura, Lanzarote, Gran Canaria, Tenerife and La Gomera were formed when the former was almost fully developed, La Palma and El Hierro “are twin islands grow simultaneously, but not simultaneously, but alternately “so that” when a lot of activity in the other there is less or almost nothing. ”

        In the last 12,000 years, detailed in the Holocene period, most recently, “there has been a massive volcanic activity in La Palma, for example, more than half of the historical eruptions are concentrated in Cumbre Vieja, while in the Iron, so far, there had been no “in that period.

        The eruption “younger” in the island of Meridian, stressed, “is 2,500 years old” and, at that stage in La Palma have been counted “over 20”. Therefore, “statistically and following the maxim of geology that says what will happen most likely in the immediate future is what happened in the recent past, it is logical that he would have played at La Palma, but the nature our observations laughs frequently, as he has had this time to iron. ”

        However, he pointed out, both “are buildings that operate independently, what happens is that in these phases of activity very quickly, grow, rise above the level of balance and collapse and, as happened 560,000 years ago in La Palma, just with a giant slide. ” This dramatic decline “resulted in La Caldera and Aridane Valley.”

        He stated that “when either of these collapses, the stress system, ie what is above the volcano, inhibits the process and moves to the next island.”

        Regarding his latest book, said that “as pyroclasts of El Hierro, still fuming.” He aspires to be “a tool that can be used.” He indicated that the last work in this field, written by Telesforo Bravo, was released in 1956.

        “Since then it has rained a lot and in geology, where there has been a real revolution of plate tectonics so that everything before that, is of historical interest, but not scientific” and therefore had to , after making “a riddle, to condense the knowledge acquired on the Canary Islands are a great many” because of research by “thousands of scientists around the world.” Has decided to distribute the work in three volumes.

        The first, filed Friday in the capital palm, “focuses primarily on aspects of generation of the Islands in the ocean, how they have evolved in the underwater stage and, finally, the risk associated with living near active volcanoes.”

        The second has advanced, will be devoted to the description of the different landscapes and types of volcanic lava. And the third, “will be an island by island geology highlighting the most important points of the wonders we have in the Canaries.” It will also incorporate “commented itineraries.”

        Lurking – you’re alternation between la Palma and Hierro gets mentioned. But the exact process is not resolved.

      2. Thanks for the translation.
        I guess for more info, you’ll have to buy – or get your hands on – Carracedo’s book…

      3. Its not my idea. He’s the lead author in that linked paper where I read the idea.

    1. Lurking,
      I’m not convinced about a hotspot-driven mechanism. Your graphic shows very few EQs in the past 30 years – a couple per year? That we should suddenly this summer get 10,000 does not give me the feeling that the cause is a rise in heat flux from a plume – too fast.
      The Canaries move with reference to the African hotspot about 20mm NE wards per year: fig 1 here
      http://geosci.uchicago.edu/~rowley/Rowley/Publications_files/ForteetalEPSL2010Africa.pdf
      But the African hotspot covers a huge area and the Canaries is but one of many plumelets identified at 250km depth ( fig 6). So I dont see Hierro or La Palma being differentially affected by a hotspot.
      Sagiya’s interest in the Canaries from the aspect of tectonic processes makes me tend toward a plate collision mechanism. We now have an unusually symmetrical arrangement of EQs at Hierro:
      – the central shallow band from July to end Sept.
      -two groups of mag3+
      1, in the south at ca 15km in Sept jsut before Bob opened
      2, in the north of Frontera now but at greater depth 20-25km. And today we have preliminary evidence for a northern subsea eruption.
      So to me the Hierro phenomena seem too sudden and too ‘structured’ to be driven by the arrival of a hotspot plumelet.
      Peter

      1. I’ve been looking for the geothermal gradient for the area… and the odd part about it is that on a global scale, the region comes up as cooler… with the maximum “coolness” to the south.

      2. As for the previous quakes… my attention was to the depth and time.

        A few went off in the last couple of years at a deeper region that most of the activity now. I’m thinking that it could have signaled melt than then rose to the current party.

        Overall… on a broad wide scale, Canary quakes deepen the further to the north you go.

      3. @Peter: There’s one big problem in your description. If the El Hierro “magma chamber” is aligned according to the rift (due to obvious reasons it is very likely), you really can not make a clear difference on the two scenarios (rift volcanism vs. plume volcanism). That’s looking at El Hierro only. To make a difference, you got to look around, at the other Canary islands. Taken their ages and geogoly, plume volcanism seems to fit the bill clearly best.

    2. Hello Lurking.

      I actually have a problem with believing that El Hierro has been quiet for 2000 years. I do believe that the all those wonderfull underwater Grandpa Bobs down there are fairly young. I would bet that a large portion of that long underwater seamount trending from La Restinga has been erupting on and off during the last 2000 years. Seriously, if it had erupted a bit further out and there had been no monitoring equipment, there would at best have been a few fishermans stories. So I could easily believe that it could be as little as 50 years since the last eruption.

      Back to your actual question. Yes, I would think that this is a return of a more active Hierran episode.

      1. But more matter of factly: In this paper (http://www.earth.ox.ac.uk/~tony/watts/downloads/Geeetal01.pdf) from 2001, the authors are implying (p. 108) that the southern rift zone would be very old, even older than the island itself and be part of the seamount on which it is built. Which would mean, the rift is older than 900.000 years (Carracedo, e.a.: Canary Islands. Classic Geology of Europe 4, p. 245.). But on the other hand, cones like the ones shown on the pictures presented by the scientists of the boat Ramon Margalef (http://www.europapress.es/sociedad/medio-ambiente-00647/noticia-asi-nuevo-volcan-submarino-hierro-20111028121653.html) seem to show cones which are not much eroded – which would undermine your hypothesis, that Bob has some just a little bit older brothers and sisters down there.

      2. Uhm, you are confusing seamounts here. The rift seamount running straight down in a slight curve from La Restinga is the active rift.

        The Seamount that are old artifacts are a bit aways.

        Second of all, how could non-eroded cones be against my theory? That is rather illogical you know.

      3. Carl,
        I was just weighing up different theories here. I know that they are contradicting each other.

      4. But if Bob’s sunmarine relatives were fissure eruptions, there may not have been significant EQ activity to alert anyone to their presence.

        I read somewhere that Surtsey may have been active for sometime before finally emerging as an island. (Can’t give reference as I have returned the book to the library).

    3. @Lurking: In principle, I think yes, it is possible. There’s one difference, which I do not really understand or have anything to value it, if it is important at all.

      At the Canary Islands, the “flip-flop” oscillates perpendicular to the direction of plume motion, and the relevant islands are about 100 km apart. At Hawaii, the volcanoes mentioned are on the same island (maybe 20-30 km apart), and they both lie along the direction of plume motion.

      There’s got to be a physical reason for this difference in alignment. It seems to me, the “flip-flops” are aligned roughly along N-S axis for these two cases. Are there any other similar cases?

  30. Everybody seems to be hanging around here and not at the El Hierro article (good for Jon).
    Raymond Matabosch, the Frenchmen, just has ended me a picture from the new vent at El Hierro – he expects “events” the next 36 hours (like Jon btw)
    Update is online at ER

    1. Thanks Armand! AVCAN also reports that the private Nautilux boat is now going to explore the stain in front of Frontera:

      Buenos Dias !!! INFORMACION . EL NAUTILUX Y PEDRO CANOMANUEL ENTRANDO EN LA MANCHA DE FRONTERA , estamos en contacto y cualquier dato lo pondremos. Saludos a tod@s

      1. No, they’re just saying that the tunnel entrance is the new vent. It is what is marked in the photo, try google earth and compare, there is no new vent.

  31. Raymond The Frenchman is almost at the end of the tunnel where he can overview the grey seaspot. I really cannot imagine that something like this can be going on without IGN and the others to communicate on. So it must be fake ! But if AVCAN is going to search for it at least there are more id… than me alone to believe it.
    I also just wrote that people at Los Llanillos do not see anything (friend of my contact living there)

    1. Longtime lurker, first time poster 😛

      And sorry to say Armand, but the ‘vent’ that’s circled in the pic on your site isn’t in the water.

      http://earthquake-report.com/wp-content/uploads/2011/09/elhierro-01112011-3.jpg

      It’s the top of the cliff, and the black/dark blob is just where the cliff road cuts into the top as it curves round. (I tried to match the viewing angle /distance)

      http://i264.photobucket.com/albums/ii196/Ryukai_San/Itsnotavent.png

      The sun is still low in the photo/video footage so shadows are larger and deeper than they are during midday, that and the bluriness doesn’t help either.

      Sorry to dissapoint 🙁

  32. I read comments somewhere today about solar activity, gravitational effect of planets, moon and sun and Volcanos. The writer was shot down in flames.
    Can i remind people that although these are meerly some peoples theories, and it is correct that no conection has been found or proved by a scientific body, that it is this kind of questioning and seeking of answers that makes a scientist a scientist. It is to some people this possible search for a link that makes science interesting.
    I think it is prudent to comment that there is no proof of any link, it is also harmless to allow people to search for any possible link.
    There is so much we do not know and as human beings we are still in our infancy in the big world of science.
    I hope the writer is not put off from using the blog and continues to contribute, any ideas, possible connections should be explored but preferrably in a scientific way with graphs etc to show their theories.
    Unless someone is linking to one of the doomsday sites or putting something completely off subject the we should allow them to speak, thats why its a blog.
    We can then of course show evidence to go against theories, but lets please have open discussions on the blog, with constructive critism where needed.

    1. Well, considering how the magnetic field of the Earth (supposedly) is generated, namely by convection in the outer core, and convection in the core also drives convection in the mantle, which in turn drives plate tectonics and volcanism, it wouldn’t be surprising at all to find a connection between high solar activity and high tectonic activity (probably with a time lag), since every major solar event (e.g. CME) twists and bends the magnetic field lines and this may well have repercussions into the Earth’s core.

      That you currently won’t find proof of this is also not surprising, because the scientists don’t really know how this all works.

      1. Interesting … I have had a hair brained idea for some time that a weakening of the earth’s magnetic field is linked to volcanic activity. My thoughts are, that a reduced magnetic field (“pull”) will lead to convective forces having more influence on iron rich magma … any thoughts?

      2. According to the dynamo theory the magnetic field of Earth is generated in the outer core, which is fluid – mostly molten iron. It also has to do with rotation (coriolis forces), (core) convection and a electric currents that flow in the outer core.
        The convection in the core is not the same as the convection in the mantle, they are separate and as far as the theory goes, doesn’t contribute to the generation of the magnetic field.
        The mantle convection is, however, important in heat removal from the core.

      3. Earth’s magnetic field is decreasing as the field is heading for a reversal. Currently the magnetic south pole lies at the northern hemisphere (near the geodetic north pole), and vice versa for the other poles. After the reversal, the magnetic and geodetic north poles will both reside at the northern hemisphere.

        The pole reversal will take hundreds to thousands of years to complete. During that time compass directions will be a mess. And, this has happened before, typically every 0,1 to 1 million years. So, no EoWaWKi (enf of wortld as we know it) is coming…

        See more at: http://en.wikipedia.org/wiki/Pole_reversal

  33. @ Jon and other experts
    A very remarkable seismic moment this morning : in between 07:16 and 11:14 NO earthquakes were registered! This is a gap due to the IGN listing or if true explains a lot on what is going on. A request to the specialized scientists : please explain.
    The video below was recorded this morning (we do not know the exact time). Might it have been possible that he we had an eruptive burst in the morning hours who did shut off again ?

    1. Not an expert, but there were artifacts in the tremor traces that point towards quakes. With that roar it’s pretty hard for gear to pull out the smaller ones.

      As for something shutting off, the din of the tremor didn’t seem to change much in it’s characteristics… at least as far as I can discern.

    2. That reminds me: How can you decide or know whether a tremor signal is actually due to one source, two or several? Do the signals of more than one source add or is just the strongest visible thus swallowing up the others?
      If you have a link where I can read up on that, that would be great.

      1. Unless you have an array of gear, you can’t really locate it.

        What I did a few weeks ago was to try and use artifacts in the CHIE trace that showed up in EHIG and EGOM to establish a rudimentary bearing cut from the baseline between EHIG and EGOM.

        As for multiple sources, they all add together.

        In theory, you should be able to do phase analysis to get a location in the same manner that phased array radars and sensors work… but that’s a lot of equipment and I don’t even know if anyone has developed anything like that.

      2. If you want to know more about it, look into a Rotman-Turner lens. The idea behind it should be usable for seismic sensors from an array if the time delays are designed for dealing with acoustic signal speeds.

    3. Maybe this explanation will be usefull for you:

      As you know, the IGN web only gives information. It isn´t investigation center web as you could think. The case is that during the last “Bob” eruption, after some largest EQ, the seismic data stopped and, two hours later started again. But with no dates, no EQ, nothing. I called us by phone to asked what happened and the told me that they are analyzing and studying the seismics data and, when they finished, the information would be given on the web. Two hours later the “lost” data appeared on the web. So, this is the IGN way to do things. I don´t know if it is habitual or not.

    1. What surprises me is the almost clear water and many small fish swimming around. And yes, as Lurkingalready said, the molesting of the starfish!

  34. Nice to see the images, but i am not excited about it – we see nothing new there – the saturated water with ash / could be seen by the satellite very clearly. To me it looks like he has now showed that his robot works and he might be gone tomorrow to Vigo again (sorry to be so negative about it)

    1. So ah… while they were down there molesting the starfish, they didn’t happen to grab a sample of the lava or ejecta did they?

      1. I have mentioned before Hot water and volcanic brews do not go well with the delicate electrics in ROVs

  35. The tremor is becoming consistently stronger today, and the main quakes are still at depth 15km or more, below El Golfo. If the smell is present at the shore, however, then this poses a danger in itself. It evidences cracks, even if just small ones so far but, with a strengthening tremor, surely this can only get worse?

  36. To add to my comments for the user that got shot down for mentioning Gravitational effects on Tetronic Plates i have found this from a respected website on the subject …
    Tectonic plates are able to move because the Earth’s lithosphere has a higher strength and lower density than the underlying asthenosphere. Lateral density variations in the mantle result in convection. Their movement is thought to be driven by a combination of the motion of seafloor away from the spreading ridge (due to variations in topography and density of the crust that result in differences in gravitational forces) and drag, downward suction, at the subduction zones. A different explanation lies in different forces generated by the rotation of the globe and tidal forces of the Sun and the Moon. The relative importance of each of these factors is unclear, and is still subject to debate.

    I am not saying its true or not but with a scientific mind then its worth looking at.

    Another theory … is that solar energy releases particles that go deep into the Earth and excite molecules during a CME, or that the gravitational effect of a solar flare leaving the sun or just prior to helps the plates move. Again unproven theories, but with a solar flare or CME expected this week i am going to watch out of curiosity for enhanced seismic activity. The last one we had Earthquake in Turkey and increased activity, im suspecting coincidence.
    But the best scientific minds are open to ideas, so i am going to watch this and see if anything in it at all. Will report my findings when enough evidence either way ( probably around the year 2044)

      1. I’ve posted it before. I just replotted the data.

        I’ve been down that road several times.

      2. I agree with your conclusion that solar flares don’t create earthquakes.
        But just one remark. The solar flare itself isn’t the criteria you would be looking for in this context.
        You would be looking at the coronal mass ejections that were directed towards Earth and have caused geomagnetic disturbances, and you would have to compare that to volcanic and tectonic activity, maybe several years later.

      3. You make the proposal, then you test it. There’s lots of data on the web to work with.
        If you’re right then you’ll get the credit.

      4. I have not made any proposal yet, I have just been pointing out the solar flare as such may not the right or the only parameter that should be look at, when you are in search for correlation/causation relationship, that’s all.
        I am sure you can handle some constructive criticism.

      5. Solar flares and CMEs occur in most cases within the one and the same eruptive event. In the rest of cases, the difference does not matter.

        There’s no physically (energetically) possible mechanism to create the causal connection you seem to wish to be there… Study physics, and you’ll quickly see that yourself.

    1. A scientific mind throws in viscocity, and abandons the idea as it simply does not work.
