Here are two videos of the eruption in Eyjafjallajökull that took place earlier this year.
This video was taken sometimes in March 2010. I am not sure when. This is the first phase of the eruption in Eyjafjallajökull.

This video was taken on the 17th of April 2010. This video shows the second phase of the eruption in Eyjafjallajökull 2010.
Truly spectacular and puts the odd steam cloud into true perspective
Marvellous! I especially like the nighttime timelapse, so beautiful. No wonder some of us are suffering from withdrawal…
What is most amazing in the Fimmvörduháls footage are the sounds produced by the lava fountains. I spent hours of my time just watching the cams during those nights and it had a therapeutic effect on me. Thank you Jón. Any more tremors / inflation at Grimsvötn?
@Renato Rio, The SIL station at Grímsvötn is out. It is just a technical fault there that can happen. I don’t know if the inflation is still ongoing at Grímsvötn, as the GPS station has not reported back it seems.
I am currently tracking GPS data from GPS station hvol and Gola on Mýrdalsjökull area. But those stations are showing some interesting signs at the moment.
Hi Jón F, nice to review the videos again, and to see different ones. Thank you.
Umm… I head off to a couple of errands and things get weird.
WARNING: THIS PLOT IS NOT INTENDED TO BE USED FOR AUTHORITATIVE PREDICTIVE ANALYSIS.
For one, Station GFUM is acting weird, not showing up, whatever. It may have even been knocked over by a yak for all I know. Only five stations were measured over their last four days of data, the rest were not used. The perimeter of Iceland was used to make the outer area of the surface and was held at zero elevation change.
Other than that, it’s a cool plot.
Elevation changes in THEY, HOFN, GFUM, SKRO, and BRUJ, perspective view.

A few nice quakes 1 about a 3 magnitude
@Lurking Nice plot nothing to worry about unless you are the yak that took out the GFUM station.
I did record the earthquake at Hamarinn. It looks tectonic in nature, but it is hard to tell from the great distance. But I did only record it at my Hvammstangi station. My Hekla station is offline, but I know that it is still recording data but I cannot connect to that station to view the data. The computer that controls the Hekla station is going to be repaired next weekend.
Ya know, I’ve seen that statement time and time again, but I have no idea how you (or anyone for that matter) can tell that from the seismo. What exactly are you looking at in the traces that indicate that? I know that comparing first arrivals can give an indication of the focus mechanism, so.. what are you looking at? Shape? Power levels at different spectra?
I notice that tremor graphs for SKR and VAT are showing a slight climb at a all frequencies and that KAL/FAG/ADA and others are only showing a slight climb in the low band.
Mean something to you?
@Lurking, I can look for magma signals in the earthquake. That is how I can tell. But with medium and strong earthquakes it is quite hard to know if the earthquake is created by magma or not. The only way then is with a special software, but I don’t have that at the moment.
The tremor plots are climbing due to a storm that is passing over Iceland at the moment.
Okay… then we are right back at the original question, but closer to the answer I seek… (possibly) “magma signals?”
“Omphalina protati?” WTF is up with Capcha? How about a semi coherent word? I had one earlier today that looked for all the world like morse code.
Watching those quakes!

@Lurking, Magma signals are different and can be spotted. They don’t look anything like weather noise. But you still need a bit of training to see them on the tremor plots on IMO.
Can you post a few pics of how they look…
@renee, Not at the moment. But over the weekend I can see if there is a image of such even at my computer that I have at home. I am currently not home, as I am in school over during the week.
And another shallow one under Mýrdalsjökull.
Must leave now, be back later for more. Txs.

@ Jon – In your opinion which would be the one to go off first? Hamarínn or Grimsvötn? I know Grimsfjall has a GPS station keeping an eye on it but how is it at Hamarínn? Are there any monitoring at that location? I mean Grimsvötn has frequent eruptions while Hamarínn has not had one during historical time..But now there has been quite a bit of seismic activity beneath it and I would guess most of it is magmatic.
@Jón Frímann, I agree with Renee. Pics if you can please.
@Lurking, See answer above. But did you get my email with your password ?
A small edit to my last post:
I misspoke when writing has not had one during historical time. What I meant was that it has not had any eruptions during our time unless anyone here was born early in the 1900´s. And one unconfirmed event after that so I guess there is not much that is known about this volcano?
@ Jon – Yes and I agree with bot renee and Lurking. A small tutoring regarding magmatic/tectonic signs in the tremorcharts would surely increase the knowledge of the volcanophiles hanging around here. Even if it is ever so slightly. 🙂
Not my intention to spam the blog so last post for a while…
@ Jon – Is it safe to say that the 1-2Hz band usually picks up harmonic while the 2-4Hz is more weather related/ongoing eruption and the 0.5-1Hz is mostly larger events like bigger EQ´s? Of course they are all affected by weather as we have seen before but if any of the events i posted above would occur would they do so within the Hertz ranges i described?
@Daniel_swe, As it stands now it looks like Grímsvötn is going to erupt really soon. But it is quite unclear with Hamarinn volcano at the moment.
@ Jon – Yes I would place my bet on Grim as well given the recent inflation. But is there any instruments monitoring Hamarínn at the moment or are there any plans now that there has been increased activity?
@Daniel_swe, The closest monitoring station close to Hamarinn volcano is Skrokkalda station. But there is both SIL station and GPS station.
Ok. Well Skrokkalda is not showing any signs of unusual activity. Lets see if the seismicity is a dual eruption (Hamar & Grim) is in the future or if it is just some unrest at hamarínn. 🙂
“I misspoke when writing has not had one during historical time.” – hehe. This is a very interesting issue we have when trying to figure out geological/astronomical scales: dimensions. It’s so natural to inscribe “historical times” within the reach of our own lifespans (i. e. as far as one or two generations before us) that you need some training to think otherwise. That’s what fascinates most me about Earth studies. We “must” face our own limits, which gives us a healthful and natural sense of humbleness towards existence. Of course there are those whose mastery of this kind of sense may lead to the opposite, omnipotent, direction.
Sorry for the philosophical blabbering. 🙂
Well “Philosophical blabbering” or not. I like it. 🙂 Try to wrap your head around this one. Some time ago I read about the definition of the word “Eternity”. It went something like this:
Imagine a smal bird. She is landing on the top of Mount Everest once every 1000 years. Every time she lands there she picks with her beak for 1 second and then leaves not to come back for another thousand years. When Mount Everst is completely gone from the face of the earth due to her picking for 1 second every thousand year….A mere 10th of a second of eternity has passed.
Every time I think im to stressed by work or anything else I think of this. It helps me calm down and realize that the time we spend here on earth is just a fraction of a fraction of a millisecond. And to make the most of what we have..because time is short!
Of course i missed the punch line. The last row in the “poem” should read A mere 10th of a second of eternity has passed and eternity will go on for an eternity!
I’ll keep these your words for the tougher moments, Daniel. Thank you.
But that doesn’t mean that, secretly, we may not want to be granted the chance to witness another Laki event (“God” forbid!). 😉
Even better!
If another Laki event or similar would happen and it would not pose any threat to anyone or anyones livelyhood (farming, animals) then it would indeed be a treat for all of us. Otherwise I would like to tell Mother earth to take its stomach problems somewhere else..Where there are no humans or animals. 🙂
No event the scale of Laki or Eldgjá can occur without having ramifications. Just the volume of gas release itself would be a catastrophe.
