Volcanos in Iceland, possible alarm?

reply to post by PuterMan


I was just watching out local news and they are reporting that the smoke has died down but as Jón Frímann says
it´s not done at all there are still exsplosions going on in the crater and with the tension not dying down it´s more like the volcano is just resting a little before starting up again. It will be interesting to see what happens in the next 2 days.

It is also really interesting how the tremor plots from surrounding area´s seem to be affected still by the eruption i would have thought that the tension in the nearby stations would die down right away after the initial eruption. But if you look at the plots that are stationed north west and south of Láki it seems to be still affected. And it also seems to reach down towards Katla.

North of Láki

Near Katla

This tension going down to near Katla is quite similar as the initial quakes as posted by the picture berkleleygal posted. Im not even going to mention the idea that´s floating in my head as it is a bit to sick to even mention. , but as i said the next 2 days will be interesting

perhaps to much melting water created an temperoral crust?... so pressure can build up??

reply to post by ressiv


This theory is actually not that far out as there have been no reports on increased water level´s and now they are reporting that there´s steam coming up to 200-300 meters and explosions with that.

Think you might be right on the money there

This is the newest photo of the crater, the steam seems to be coming out of 2 craters there in the middle as you can see a little space inbetween the smoke, but the most interesting part about this photo is the water in the left crater there seem to be swirling which means it draining all the water below. So Ressiv might be right on the money about the crust.

O.k very impresive,, golf clap everyone

reply to post by Spacedman13


Wow,, so water & lava not good then,,and how big is the hole that went BOOM ,, cause all that material didnt come out of those two holes.

reply to post by BobAthome


That actually is not a small hole the picture just makes it look like that, but when it started it might have been spewing out from the area´s that are now coverd in water. But that is just speculation on my behalf.

reply to post by Spacedman13


Ya thats what i was wondering ,,could it have been filled that fast?,, earthquake,breaks,wall,watergoes in, BOOM,
water now below breach, and swirling??

Thought you might enjoy this gif showing the start of the eruption in a couple of frames.

Well that is a good question, i think i´ll have to take a pass on that one and ask if Puterman could answer it. But from my memory i have never seen a crater that has a open hole that shows the lava below except for of course hawai. But then again that´s not a crater i saw there but rather just flowing lava all over. The crust does really quickly settle in, found this movie clip from the telegraph which shows the crater and as you can see from the start of the video the ground there really looks solid then it tosses up like loose dirt. www.telegraph.co.uk...

Never mind my previus comment as i looked again i noted the ground was actually water , just really really mud coverd. Also listen to the video when it starts up the footsteps slowly come closer to the camera and then he moves to a safer distance. Wery Wery slow walking, i would be running put apparently that´s not the correct thing to do.

And this link i of course found on the most informative blog you can find. www.jonfr.com...

Is it the Hydrogen Atoms that Explode,, or the power of Steam in a Compressed area? thats a lot of juelles

Thought i would add one other photo , this is one of my favorite ones.

There are a few that show the lava, including Hawaii. I think this one qualifies. That is Halemaʻumaʻu Overlook Vent, Kīlauea Volcano

The most famous (probably) is Erte Ale and another one is Ambrym - Vanauatu



....and perhaps a bit tamer Nyiragongo - Congo. Mm, maybe not tamer!

Which do I believe? Vedur of course!!

Just been reading Jon Frimann's Blog. Seems there's no cause for alarm at the moment.

I know you worship this guy.

I also know that a major Katla eruption is no laughing (out loud) matter.

How much 'harmonic tremor pulse' would give cause for concern in your opinion (ATS respected BTW)

Thought i would bring this article to the thread in light of recent activity around Katla.

Katla: the sleeping sister

Getting some activity at Langjokull.

edit 1
Seismic activity and not volcanic of course

These quakes that are most really shallow ones the deepest quake is about 2.7km in the caldera while the rest is mostly ranging from 0.1km. But i would have to put this one the heat that´s finally starting up it´s been really cold and the weather just got a little better. So maybe it´s ice melting causing cracks in the ice that might be showing up on the meters (atleast for the shallow ones).

This is the latest tremor chart from Godabunga the central one for Katla and there does not seem to be a increase except for the one starting now but that might just be another spike like the one you see around the 11th. Source of pic
[atsimg]http://files.abovetopsecret.com/images/member/533da15d75b8.gif[/atsimg]

As for the quakes around Langjökull we had a huge spike in activity there last year around this time, think it might have been a little later in the year but im not sure. Last year there was a huge swarm that happent there and it reached all the way up around Hofsjökull to the right of it. But nothing came out of it, yet it was the first activity there for many years , if im not mistaken before last year the most recent activity there was before Hekla 2000 eruption.


And we did talk about Langjökull somewhere previus in this thread about the last years quake activity. Just scrolled back through the thread and it is on page 8 that we talked about the activity there it seemed to have started last year at the same time the Krýsuvík area started to show some signs of unrest.


*Edit* Just read Jon frimans blog, and for once i hope he´s wrong

Some occasional activity around Katla throughout July. Jon Frimann's blog provides a good summary.

www.jonfr.com...

Hey hey everyone hope you all have been having a good summer, i most sertenly have.

We got ourself a swarm of quakes in the Reykjarnes ridge area, which is of course normal but there are a few larger quakes in there. Largest one is 4 followed by 3.6 and a 3.1 richter. And of course while this is happening they are reporting that there is a chance that eastern Skaftár which is located at Vatnajökull is producing more glacier meltwater. Which should count for the tension measurements at Vatnajökul at the moment. But seing as Skaftár just recently had a outburst of water this time around it should not be as much.

Total Quakes: 48

I was wondering about one thing that i had not really thought about that much, when looking at the tremor graphs i found out that spikes in the maps just meant minor quakes or some sort of disturbance, wind ect. And sharp spikes that kept steady mean increased tension, magma flow and such.

But i had never really considerd what the lines in the left mean, not really sure how to describe it , so im illustrating it below.
-------
3000
--------
2000
--------
1000
--------
0
--------
-1000
--------
-2000
--------
-3000

So basicly what i was wondering is compared to a erlier picture (a couple of month ago when krísuvík area starting to act up) the graph looked like this
[atsimg]http://files.abovetopsecret.com/images/member/b8b4975ccaf9.gif[/atsimg]

But now it seems that each "Hz" is up about 1000 in the picture below

[atsimg]http://files.abovetopsecret.com/images/member/8c834f9e45ee.gif[/atsimg]

So my question is what do the lines in the left mean , and does it mean that there is increased tension overall in that area?

(if so i´ll be kicking myself because this is something i would have liked to start observing erlier and copying the data for that)
