Large earthquake swarm in Katla volcano

At 02:45 UTC a large earthquake swarm did start in Katla volcano. I do not know if this an start of a eruption in Katla volcano or not. For the moment it is too early to know for sure. I have to wait few more min before that becomes clear on the harmonic tremor plots. The largest earthquake so far according to the automatic SIL systems is a ML3.9 earthquake.

It takes a few moments to become clear if Katla volcano is starting a eruption or not. I am going to post updates as this situation changes if I have too.

  1. First time I’m in on this blog – being a novise I might have a silly question.
    I am looking at the webcam… is it possible to know where an eruption will start? – left, middle og right side of the glacier ?

    1. Maybe he is like superman and shaking the the mountain and causes these issues. 😛

      2. Dancing on katla 😛
        Creating the quakes, that would explain why he misses the action 😛

      3. He was practising his nude dancing on Ice and eating giant Mexican sombreros and Katla rightly got offended. 🙂

    2. Carl is probably on his private jet right now and will contact us over his solar-powered, satellite-relayed laptop from a vantage point at Fimvörduhals or suchlike. 😉

    1. Probably saying you’ve been warned for months and your really pushing me and asking for it!!!!!!!!!!!!!! 😛

  4. I love clicking the translate on vedur.is when a message from Earth Scientist appears. This morning’s is

    From the start at 2:50 sharp in skjálftahrina Myrdalsjokull just over an hour later, a second smaller and less than a third cycle followed soon kjöfarið. Thereafter, single seismometer, but their frequency has minkað significantly. Seismic wave response were in north-eastern Katla caldera just south of the huge dome-shaped Austmann. About 20 earthquakes were larger than 2 points, including several larger than 3 points. No one attended this unrest episodes. Increased activity has been Mýrdalsjökull recent months but this is a major pasta cycle to date.

    I just love the “major pasta cycle”

      1. Lava bread and Tufa ..ghetti
        (lava bread is a traditional Welsh dish made from seaweed 🙂 )

      2. Sorry to be pedantic Diana but it is laver (not lava) bread. Mind you if I made it then no doubt it would be as hard as lava bread. 😉 Thanks for the laughs anyway.

  5. So, I have to leave the computer now.. I really wish there was a way I could get notified if anything more happened. I guess I just have to wait and see for myself when Im back home.. No chance I’m gonna miss an eruption just because I’m out for a few hours…

    1. Don’t let Katla see you go. Creep out quietly. She ALWAYS acts up when I go out or I am asleep.

      1. Hehe well..Yes..You got a point there.
        I think i wrote before i thought about it..

        My meaning was an increase in meltwater which would lower the temperature. 🙂

  10. Wednesday
    05.10.2011 11:24:37 63.639 -19.052 1.1 km 2.3 90.02 7.0 km NNE of Hábunga

  11. Wednesday 05.10.2011 11:37:35 64.057 -21.375 3.4 km 0.8 62.27 2.5 km NNE of Hellisheiðarvirkjun

    1. Hopefully just geothermal drilling / pumping water as part of that geothermal project.

      Not too sure I’d be that brave with a visibly restless Katla.

  12. There were many earthquakes at depths we are not used to see, especially in Skógar and Godabunga.

  14. Katla is mentioned in Estonian media too. Jon was quoted. http://www.delfi.ee/news/paevauudised/valismaa/islandi-vulkaani-katla-all-variseb-maa-kardetakse-purset.d?id=59148396

    Translation:

    Icelandic seismological stations have registered a series of earthquakes under Katla volcano. The strongest of the earthquakes was that of 3.9 magnitude. On Tuesday automatical devices registered an earthquake whose power was 3.3 magnitudes, as passed on by Ilta-sanomat. “I do not know if this an start of a eruption in Katla volcano or not,” wrote Jón Frimann, a blog-writer who is monitoring the situation, on his site. Often a series of earthquakes precede a volcanic eruption. The quaking of the earth crust is common in Iceland and one cannot claim that a big eruption is forthcoming.

    1. The “Ilta-Sanomat” mentioned is a Finnish afternoon newspaper. And they had basically the same content in their article.

      1. “iltalehti” had a bit more sensational story, allthough nothing i didn’t know from this blog already in morning 🙂

  15. to ignore the abundance of evidence that the other half of our solar system is approaching is tantamount to willful blindness and that alignment of planets on the ecliptic causes large volcanoes and earthquakes… never a straight answer NAZSA is over run by bilderberg nwo reptiles and should not be taken seriously logic and common sense tells me the other half of our solar system is coming . earth and the other planets orbit the sun for billions of years without both wheels on our binary solar system spinning off one another we would slow down and stop spinning and orbiting the sun the solar system is a binary motor with two suns and two sets of planets spinning in opposite direction getting close enough to one another every 3600 years to propell one another for another 3600 year orbit and 2012 is about the time of its passing

    3. What on earth are those ramblings supposed to mean? This is normal geology we talk of on this site. We don’t talk about science fantasy!

    5. No, you are wrong.
      It is all caused by icelandic robotic sheep.

      Howard, you are extremely shutupolicious. I have waited so long to use that word.
      Please stop spreading unscientific Hogwash.
      Bilderberg is a Hotell. NWO is a bar in Bronx and the reptiles taste like chicken. Get a life.

    6. I too have a revelation – Tomorrow Jesus will come down in a spaceship and take off the disaffected to Second Earth which co-orbits and is always behind the sun, a world where magic works and the Noldorin tongue is still spoken.

      Sheesh…

      2. I don’t know what they take – but I think I would be happier if I took the same shit…
        How can I concentrate on my f… work when there are people offering me so much entertainment???

      3. Let’s not forget that there are people believing that dinosours are the result of the devils creational efforts – erm, lets say 6’000 to 12’000 years ago.
        Shouldn’t we try and give them some respect?…

      5. I feel a bit bad about how I put it. Let me try to say something nice. Eeeh, ouuuh, aaaah, hmmmm. Yes, now I know: long life to all interstellar powers diffent parts of mankind believe in.
        Naaaah, I’m not good in this. Let’s try something for the 2012ers. Erm, not easy at all. Yesss! Positive thinking: Guys, it’s not only a year left, but the chance to have STILL a year.
        I’m getting tired. Should go home and take time later in the evening to enjoy this shared excitement.

      7. If we could reason with religious people, there wouldn’t be any religious people!

      10. We have an atheist here is Sweden who reminds me of Ayatollah Khomeiny if you put him on speed. He quite literally starts shaking and and screams untill he falls down in fits when he is talking about the dangers of religion when is on TV…
        I sometimes thinks he will be the next generation terrorist together with vegans…

      11. I’m with Jack – as is Stephen Hawking who is a damn sight smarter than any of us!

    9. “logic and common sense”

      I don’t think those words mean what you think they mean. . .

      I think the microchip the bilderburgs planted in your head needs a rom update, dude. Better hang out in an open field at midnight on a clear new moon evening and get that taken care of.

    1. Looks like it since the quakes has subsided. May be some hydrothermal aftermath. Would be nice to see if any new cauldrons has formed int the area of activity today.

      1. But the waterlevel and conductivity is starting to flatten out now so maybe the flood (if there was one) has reached its maximum and will slow down soon. Then the tremors would decrease as well (if they are not magmatic).

  17. I beleive this station went offline about 4-5 hours ago so you cannot see the decrease in tremor that happened on other stations

  18. Here I take a couple of days off to do some actual working, and all hell breaks loose.
    After checking I would like to point out that it looks like Katla is inching its way closer to an eruption, and that it is moving pretty much exactly on the path for an eruption sometime May or later next year.
    We will se activity like this for weeks constantly before an eruption occuring.

  19. And Jon has been quoted here too:

    http://www.wired.com/wiredscience/2011/10/earthquake-swarm-keeps-icelands-katla-rocking/

    “Last night, Jon Frimann noted that a new earthquake swarm picked up along a linear feature under Katla. So far, there is no indication if a new eruption or flood, but it does show that things are still very active under the ice at Katla. Jon noted that so far, there is no sign of harmonic tremor, the usual harbinger that magma is moving and an eruption might be in the cards and when I checked this morning on the Icelandic Meteorological Office page, it looked like the swarm was over, with a total of a few dozen small (<M4, most <M3) earthquakes between 00:00 and 06:00 (GMT). Most of the earthquakes were between 7-9 km depth, so likely this was an emplacement of magma beneath the caldera – the question would be if that magma is eruptible or merely an intrusion at depth, a very common occurrence in a volcanically active terrane like Iceland. However, any activity is well-worth noting as other volcanoes in Iceland have seen similar patterns of earthquake swarms for months to years before an eventual eruption, so Katla will be watched closely."

  20. Thanks to everybody who wonders where I am and so on… 🙂

    Thing is that I do work now and then, but I bunch it together so that I work like crazy for a couple of days, then I go back to lazily drift along in life. So, do not get surprised if I disapear now and then.
    And also, against popular belief, I do not use private jets, and my name is not Bård Ekers, we just have the same exact modell of a car… 😉

  21. 3 new quakes in Katla again.. 2.8 at 0.0 km depth.. 90%?
    Activity is picking up wonder if it continues the next days..

    Sander

      2. No, I am looking at another list of quakes. The IMO has 3 different lists, and sometimes they are a bit different from each other.
        This is not the quake that just happened. We where talking about an earlier quake here. Down at the bottom (now) we are talking about the new quake.

      3. Gets confusing with the amount of quakes and the changes. Note to self must mention time of quake 🙂

      4. The display on the webpage always lags a bit behind, since the data needs to be processed by a computer first. Its now on: 2.9 in 1.1km depth.

  23. For those wondering about rifting eruptions in the Dead zone.
    We know how they start.
    1. First you have large scale seismic activity as the rift opens up and a dykelike sil forms. We know this from eyewitnesses of the Laki eruption. How large they where are hard to know, but they where scaring people over at Irpsits place, so we can suspect that they where above 4M.
    2. The rifting is not caused by magma influx, it is caused by the tectonic movement affecting the fissure swarm of the volcano in question causing it to rip open.
    3. There seems to be historical evidence that sugests that they rip open according to dormancy. Ie, the fissure that has had the longest time of dormancy will be the one that erupts. I think the reason for this being that the latest eruptee is to ductile to fracture in the fissure swarm since the material is to warm. So, no Laki eruption coming. If holding to the pattern it would therefore seem to be time for Katlas Eldgja fissure to erupt, but activity in Hamarinn (subfeature of Bardarbunga) suggests that it could perhaps be the Veidivötn fissure swarm again.
    4. After the fissure is riped open the magma flows from the central volcano into the fissure. I think that the reason for this is simple, it works like vacum suction-pump.
    5. You can probably see this coming before any large quakes starts. You can measure mountain strain. Short (relatively) distance GPS comparisons, tremormeasurements done inside the Dead zone, InSAR and Buguer gravitetic anomaly mapping, and magnetic change mapping. None of this is being done today as far as I know.

    The current paradigm at IMO seems to be that they will spot activity at the central volcano first. I have 2 problems with this.
    1. If they are correct. They will not be able to differentiate what is happening from a normal run of the mill eruption that is upcoming.
    2. I do not think that it is caused by the central volcano, all it needs is a filled magma-reservoir to suck magma out of. Think here of the fissure being a straw, the magma-reservoir being a milk-shake, and you suck so hard on the straw that the milk-shake comes out in unexpected places. If I am correct that a Eldja/Laki/Veidivötn massive fissure eruption is first caused in the fissure swarm itself, then they will never get it untill it is to late.
    Normally I think that IMO is really good at what they are doing, but over at the Dead zone they are playing it a bit loose… I wish Jón could put a helicorder over there, I wish it enough that it might be an idea to check what the additional cost would be…

    1. Remember the 1912 Novarupta eruption of Katmai? Magma had been collecting under Katmai central volcano for quite some time. Then a fissure opened up miles from Katmai into which the magma emptied, draining the magma chamber “from below”, and erupted creating the “Valley of 10,000 Smokes”. Last of all, Katmai collapsed into it’s now empty magma chamber.

      Very similar to the scenario you paint here Carl!

      1. Actually, Katmais Novarupta eruption (tårta på tårta) is very similar to what happened at Askja when the Sveinagja Graben fissure swarm riped on open in a northern fissure swarm eruption.
        There you had the Viti explosion (explosive caldera formation) at the same time or slightly after the fissure swarm erupted, then after the eruption stoped you had a subsidence caldera formation as lake Öskjuvatn came into being.

      3. Very pertinent observation Henrik; the long Katla goes without a full-blown central eruption, the more concerned I am that the magma will find its way somewhere even less welcome.

        Mike

      4. Mike, that might turn out to be a blessing as a very large eruption directly under the Mýrdalsjökull icecap would send cubic kilometers of ice mixed with ditto ash into the stratosphere, going even higher as the water acts like a JATO. Then imagine the remainder, tens of cubic kilometers of ice/water crashing into a not completely drained magma chamber for an even greater encore as the volcano collapses over the half-empty magma chamber…

    2. Hi Carl… Just thought I’d point you at the comments on the previous post – I thought I spotted some worrying correlations and distributions of harmonics in the nearest stations to the Dead Zone. It’s probably just coincedence, as Jack has pointed out, but given these comments, I thought you might like to look into it yourself…

      1. I did, and I concur with Jack on this.
        We could on theory see when magma was gushing into the dykesil forming as the fissure opens up due to tectonic rifting. But that would be after severe earthquake activity.
        To see what you are trying to see we would need equipment inside the Dead zone. Something that we sadly so far do not have…
        But, there is something that we perhaps can see, even though it would be circumstantial. That is increased activity at Hamarinn (there seems to be that, but I am honestly missing earthquake activity there to actually believe that we are getting close to a Bardarbunga Veidivötn fissure-swarm eruption). The other would be Katla having larger than normal activity around the northern part of the caldera.
        The latter we are seeing, only problem is that we do not have a clue what normal activity is when Katla erupts, either normaly or in an Eldgja style.
        No, we need equipment at the Dead zone to see more clearly, and we are currently a minimum of 3 years away from having a reliable system of borehole strainmeters, SIL stations and GPS:es in place there.

      2. OK – thanks. Guess we just need more sources of data, then. In the meantime, could you position a specially-trained elephant in the right area? They’re good at detecting infrasound, I hear.

      3. My powers of emplacement is as always in the hands of the Icelandic Government as they move in truly mysterious ways…
        Elephants are way to cool to place in that kind of environment 🙂

  26. Well… I got stuff to do.

    But I did piece together a quick rotating 4D of Katla with all quakes in 2011 until 5 Oct.

    No time to kludge together a terrain overlay, but I did label two of the seismic stations for spatial reference. (the Godabunga cryptodome area stands out quite well)

    Enjoy.

    http://www.youtube.com/watch?v=UCZsz1yR23g

    1. Really nice, thanks.
      Amazing actually that one can see the 4 points of interest so clearly separated.
      Godabunga is clearly not involved in the action. The odd southern thingy is a field of its own. The 1755 eruption caldera fissure is sharp like a line, and the Austmannsbunga area is like a large powerfull blob.
      Cool… 🙂

      1. The other things I picked up were the lack of well-defined (seismically) feeders or conduits… which implies to me that things must be pretty open down there. A suggestion of something trending up to the cryptodome from the southwest is all.

        And the southern hotspot seems to be isolated and rootless, seismically – very intriguing! Thanks Lurk!

    2. I’ll put that on my 42″ TV tonight and it will lead me into deep sleep… 🙂

    3. Katla seems to have a sense of humour; the red dots resemble a question mark (?). May be something orginating closer to Godabunga then moving round the caldera.

      I would not be too comfortable in Vik, having seen this.

    4. Thanks for that wonderful animation, Lurking! For the first time I’m less than sanguine because of what it reveals. Remember, there are no earthquakes inside a magma chamber but the size and shape of it can be inferred from where it obviously is not. The videogram reveals a vast empty central volume, ringed by quakes. The quakes are on the perimeter and since they are relatively shallow, it’s easy to jump to the conclusion that pressure is lifting the lid so to speak. Now, it’s anyone’s guess as to how much of that magma is eruptible…

    5. Love to see it updated when you have had the time to put the terrain overlay on it.

      Is anyone looking to see how the earthquakes generated by the drilling near Hengill are being transmitted through Katla’s magma chamber(s) to get an idea of what size / state it is in?

      1. Don’t get your hopes up, the only terrain data I have is pretty low resolution. Iceland is no available via CGIAR-CSI (shuttle derived topography… aka SRTM). Why? Dunno. But it’s not there. I have to use infill topography for areas outside that coverage area. The resolution of that is not as good.

  27. Loving all these updates! Boo,, its snowing again up there…

    Off topic, does anyone here study / monitor the Eiffel volcanic hotspot in Eastern Germany?? It could become active again at any time from what I’ve read. That really would be a Eurozone crisis!
    Thanks for all your amazing efforts Jon!

    PS: Never feel the need to apologize for things you may slightly misjudge! It’s not an exact science. James

    1. Hello James, Suppose you mean Eifel in Western Germany?
      Would like to know more about it, but really hope the hotspot it is in a very deep sleep as I live close to the Eifel (south Netherlands).
      – Always asked myself where the hot sulphur smelling water in Aachen comes from anyway.

      1. Hi Sissel, Sorry! Yes… I got my east and west all confused.

        That is a very, very dangerous volcano complex. tick-tock-tick-tock. 😉

      2. About as dangerous as bowl of water…
        It would take a long time for that one to reawaken. Even if it started to get active in full swing you are dead of old age before anything happened.

    1. No, she is doing what she always does, gearing up for an eruption.
      We will see these quake-swarms come and go for months or years. They will probably come more and more often, untill we see a period of almost constant quaking with 100s of 3s and 4s, a period that lasts for weeks, then… Boom…

      1. so i guess this ‘one off’ event doesn’t really meant an eruption tml or day after. I guess Katla need a few of such events to erupt

      3. No one knows. Katla’s last eruption happened before modern data gathering. All volcanoes are different and each eruption at a given volcano is different. Of course there are trends and parallels, but there are also many cases of sudden unpredicted behavior — including in Katla’s case as Jon mentioned recently. An eruption could happen at any time, but yes more likely we’ll see a run up like Carl and Jon describe first. Meanwhile, we’ve seen increasing activity for months now. So stay tuned!

      5. Carl, many months ago, someone posted that they thought that if there were a large quake at Katla over 4 that this would start the process of gas rising rapidly upward like a champagne bottle being hit hard where the cork is barely attached. They surmised that such a large quake would catalyze an eruption.

        It would seem this hunch is not being proven out now and in fact, you state the eruption process would take weeks of large quakes.

        I am wondering what the basis is for these 2 lines of seemling divergent lines of thought. It would seem Katla has a large capacity to hold back magma.

      6. I would say that a powerfull +4 could probably actually do that. But then I think we would need something well above 4,5M or perhaps even a 5+ quake. But the theory of a gas release explosion is in theory sound.
        But, we have not seen a 4 quake yet, so something as week as a 4,1 could perhaps do it, but it is not really likely.
        The reason for the divergence in thought is lack of known fact and behaviour of Katla.
        Yes, Katla has a rather humongous magma-reservoir that logically should be the size of the caldera. And probably some extra reservoirs at various depths. So yes, she can take large amounts of magma.

      7. Just to check – an M4.1 is (32 x log 3) or ~15 times(?) as powerful as the M3.8 we just saw.

    2. Probably not. The earthquakes may indicte a minor eruption under the glacier, other geothermal activity under the glacier and / or Katla is gearing up for an eruption proper. Which is why the IMO is watching Katla closely.

  30. Just a question, how similar were the 1955 and 1999 event’s compared to this years event? I am not just talking about the plausible eruption event back in July, but this whole summers increased activity. I see many seem to be so sure we’re going to have an big? eruption very soon following this summers activity, but can we be so sure? (i am sorry if i bring a question already asked and answered several times!)

    1. No, you are actually quite correct to question the paradigm of imminent eruption. Katla may very well go back into dormancy.
      As far as it differing? Well, it seems to be quite like each other. But this time they found a slightly less dubious evidence of a micro-eruption having taken place. I am not that convinced…

      1. Just a question: would they have been able to detect micro-eruptions in the past, if they were hidden under the ice-cap?

        It took IMO some time before it opined that an eruption had occured in July – and this was with all the monitoring they have available now.

      2. I do think they would not have been able to detect it before. Remember that the upgrades took place before and after Eyja eruption. Before that it was not as good as today by far.
        And just some fifty years ago there was nothing there to measur it.

  34. A new large earthquake did happen just now in Katla volcano caldera. It is larger then ML2.9 size given up by Icelandic Met Office web page. I can tell from my geophone at Heklubyggð location (close to Hekla).

      2. haha see my response (above), preliminary IMO result in:

        Wednesday
        05.10.2011 15:32:27 63.649 -19.167 1.1 km 2.9 90.1 4.2 km ENE of Goðabunga

        Finally beginning to understand how to read the helicorders.

        Jon at the mo I can’t donate but have been using your amazon store when I’ve had to purchase stuff. Your helicorders are great as they allow us to verify if a quake is real or not (obviously not 100% but it is a very good indicator). Anyone reading this, please use Jon’s store (adverts on right hand side) to buy as he is doing really valuable work. Christmas is coming too so if you buy a book/cd etc get it from there.

      4. Yepp, ordering books is a good way of doing good during your ordinary life. I just wish I could click a link here when buying my airline tickets… *hint*

    2. Oddity… IMO shows another 2.8 quake 90 mins earlier…

      Wednesday
      05.10.2011 15:32:27 63.649 -19.167 1.1 km 2.9 90.1 4.2 km ENE of Goðabunga

      Wednesday
      05.10.2011 13:55:54 63.624 -19.117 0.0 km 2.8 90.01 5.0 km N of Hábunga

      which obviously doesn’t exist from Jon’s helicorders… bloody big ghost though, not sure how that happens.

      Mike

      1. Sometimes my geophones do not get the earthquake waves. If the fault line is in some odd directions in relation to the location of my geophone. I am not sure how and why this happens. A some type of shadow zone appears for some seismometers and my geophones.

        But sometimes I have missed real earthquakes because of this phenomenon in the Earth crust.

      2. Actually I think what you are “seeing” or perhaps more correctly, not seeing, is a sonic gradient.
        In short, what deadens the sound as it moves is it either being reflected, or absorbed by viscous media. In the later case, what you are “seeing” is the a body of magma that absorbs the soundwave as it propagates.
        You could see it as a saline border in a body of water. (Classic problem for hydrophones)
        http://www.sciencedirect.com/science/article/pii/S0167278908002388

      3. But with hydrophones we would deploy difar hydrophones above and below the gradient. worked well for chasing Russian subs in the 70’s . From Kelflavik, nasty place in the winter

        so what we need is a ground penitrator geophone

      4. Yes, but with helicorders you cannot deploy them at various depths. 😉
        At least, unless we drill a deep hole…
        Developed the hydrophones currently in use on subs…

      1. I think they’ve had some recent issues with the automated system. Always go by the IMO page (link below). Until it accuracy is 99 (i.e. manually reviewed – which can take some time) the size can vary quite a bit – as many have commented over the past few weeks. You’ll also see depth changes too. They (IMO) are taking their time on the large ones (they are at 90% still) which is good as accuracy is very important if anyone is to know what is going on in Lady K. 🙂

        IMO (for Katla)
        (Use the Tab to see Table)
        http://en.vedur.is/earthquakes-and-volcanism/earthquakes/myrdalsjokull/#view=table

        You can also use Jon’s helicorder which gives an indication of size but with the caveats Carl/Jon have stated above

        http://www.simnet.is/jonfr500/earthquake/tremoren.htm

  37. Next blog post about the activity in Katla volcano are going to be around 20:00 UTC after the evening news in Iceland.

    I am also going to post some pictures of the largest earthquakes that have been taking place from my geophone system. Along with corrected size and depth.

      1. @Carl et al.
        Sorry for absense, been “lurking”. Nice to be remembered. But I am monitoring, you can bet…

        Unshure too what Katla will do next, I expect almost anything can happen, in next few days even – remember its traditional Katla eruption “season” and most “conditions” have been met.

        My “geans” are kind of itching, they apparently trace “back to the past” to area south of “the dead band”.

        It worries the parallell shaking in my back garden, plus if (possible) swarm off the Reykjanes ~ Krisuvik area. This even might energise your favorite hill (Hekla). Seems Katla possibly (traditionally) follows previous patterns, but try not speculate on this. The nights swarm seems to closely follow the skr station (15 hrs) “cycle” (“Dead band cycle” or the Volcanoes nearer to North).

        Does this match your thinking?

  38. OT: PayPal Question:

    Up till now I had no problems using PayPal, it would just seem to deduct money from my associated bank account, no problem .. Now it is saying “no Money in PayPal account” … can anybody enlighten me as to what is going on with PayPal, and how to clear up this problem ???

      1. ahhhh i guess I only can view it tomorrow morning due to the time lapse. Jon, is things slightly better than last night? When I saw your post about Katla about to erupt in a few hours time, my heart nearly jump out!

    2. I had a recent issue with PayPal having to wait for it to clear the bank. Ticked me off to no end. It used to just bop on though.

      It was probably a bank thing in my case.

      Thank You Dick Durbin, Barney Frank and Criss Dodd for covering your arses and screwing up the US banking system.

  41. Have you made sure that you have a valid credit/debit card on file. PayPal doesn’t let you make instant transactions anymore unless you do.

    Hope that helps.

    1. I think Boris is Joking, if I am correct, they are experimenting with geothermal pumping with carbonated water to try and create energy?

      Can an expert please correct me if I’m wrong! 😉

      2. One idea is that the H2S and CO2 will react with the hot basalt and form particulates that prop open the cracks that are generated from the hydrofracking near Hengill.

  44. Thanks Carl, I did know that it wasn’t at Katla but place had just escaped my mind! 😉

    1. Bah…. midi. By far my favorite midi track is E1M9 Hiding the Secrets from the Doom series.

      Oddball story for you. A fellow instructor I used to work with had to have some objective for the class after teaching them how to put a Sparc 5 network together (Sun OS) and getting it up and running. The final lab had them bringing it all together and running a Doom session. Using the real world network app was out of the question due to security concerns. (These were techs, not operators) and Doom fit the bill. I think that lasted all of about a month before the powers that be coffed up a more benign application that proved connectivity and concepts.

    1. I like discworld stories, haven’t read the books, but played games and seen couple of movies, have been looking for them in dvd… sorry for OT

  48. Carl, as the T-shirt says.. “Don’t F*** with Iceland! We may not have Cash, but we’ve got Ash!”

    Can’t wait to get back to Iceland! 🙂

    1. Thanks very much for this link.

      What a beautiful, though scary sight she is. Even scarier from 1000m above sea level, as a I saw her in July at Porsmork!
