Volcanos in Iceland, possible alarm?

reply to post by boo1981


Thanks for sharing that link, it has some interesting info in it.

I did find your quote from that site, and the rest of that paragraph provided some additional info that I think might be of value to the discussion as well:

"In the same presentation Einarsson said there is nothing to indicate that the volcano Katla in Mýrdalsjökull glacier is about to erupt as some scientists thought might happen following the eruption in Eyjafjallajökull. In regard to the earthquakes on Saturday, Einarsson said they aren’t especially powerful but still interesting. “There was a series of earthquakes by Hamarinn about eight or nine months before the eruption began in Gjálp in 1996 and it is believed to have been a part of the lead-up to that eruption,” he said. Hamarinn is a special volcano at the ridge of Vatnajökull and is part of the phenomena which forms the active area in the glacier, along with Grímsvötn and Skaftárkatlar. "

Does anyone on here know where to find the historical data for the above mentioned seismic activity in 1996? Understanding the past helps to understand the present.

Well from my search i can not find any data for this event, found 2 pages that were suposed to have info but one was missing and the other had a 404 error. But i was able to find the dates of the eruption and when the quakes happent.

These are the quakes that happent in febuar.

Week 1

Week 2

Week 3

Week 4
[atsimg]http://files.abovetopsecret.com/images/member/ff808b05c27d.gif[/atsimg]

Inbetween the febuary event uptill 2 weeks before the eruption there were about 50-70 quakes in total for the 6-7 month period before this happent. Wich is a really low number if you spread it out, less then 10 quakes each month.

2 Weeks before. About 2 quakes the size around 3 on richter

1 Week before. Notice that his image is about the same as we see each week now.
[atsimg]http://files.abovetopsecret.com/images/member/65e531b1e6a0.gif[/atsimg]

Eruption week. About 339quakes
[atsimg]http://files.abovetopsecret.com/images/member/556a91cb4cec.gif[/atsimg]

U can see the quakes for each year on hraun.vedur.is...

When you scroll through the list of quakes if you see alot of quakes in one region in the middle of the country, back then it used to mean that there was a eruption immenent or there allready was a eruption. But now we are getting as many quakes and nothing is happening, and with so many volcano´s overdue. There´s something sinister going on.........

Just thought i would toss in last weeks picture and description of quakes.

The country seems to be a bit more violent now then it was back then

Thank you so much for the time and research you put into this. Those eq maps are postively stunning. Especially when you posted the comparison images with the recent activity.

The weekly perspective that you provided shows a clear timeline. Almost humbling.

And absolutely, it does seem like Iceland is much more angry nowadays then back in 1996.

Definitely have to keep watching and montioring this area, even more now than ever!

Many, many, thanks for your response to my question.

You may also find this one interesting. I believe it is in the PD but I cannot find it again to give you a link so I have uploaded it.

U can see the quakes for each year..

Mm, YUM!!! 227,000 approx lines of beautiful data I have been searching for for a long time!

Thank you so much

I am going to get all that lot into my database over the next few days.

Not being greedy (much) but that lot stops @ 2009-10-06. Any idea where I can find the rest. (Speaking Icelandic would be useful!)

I am very soon going to be able to scrape the pages to get the data every five minutes (the program is done and works - I just have to incorporate it into the windows service that downloads USGS, EMSC and GeoNet New Zealand.). The program also downloads the Iceland maps and graphs every hour or as often as you like. Release date soon.

You greedy greedy man , just can not get enough data can you

From what i can see is that the data is there, when you go into the 2009 folder you see some months and it stops like you say after May, but below that are folders called "vika1-53" translation "week1-53". Should be all there, let me know if im misunderstanding you.

It was my pleasure, doing it got me a idea that i might put into place so it was a win win situation

reply to post by Spacedman13


No, never have enough data. I feel very thin on data, I have 441,000 earthquakes in my database to which I will add these 227,000 and the bulk of all that is only a few years of data. I am working on New Zealand next - started harvesting today beginning at Jan 2009. Definitely looking to pass the 1,000,000 mark soon.

Thanks for the translations. I signed on to an on line Icelandic course today. Don't know if I will have time to do it however.

reply to post by Spacedman13


Well it was awesome. Again, thanks!

But now, I do have another question. What is that other hotspot right now in Iceland? On the pic here, the area with all of the blue eq's? The area west of Eyjafjallajökull.

The area you are referring to is called Hengill, after Bárðabunga this area is the most geothermical area in Iceland this is also the most quake active region in Iceland constant action here. I am deeply consernd about this region as it has alot of volcano´s that are dormant and it is also the closest to our capital city. Don´t have the time to go into details right now but i will toss together some more fun facts for you later tonight. My beginning post referres to this region and Puterman has gatherd some information also in his posts, should check them out also.

We have some action at Vatnajökull near Bárðabunga

These quakes are incredibly shallow, the last one is only at 0,8 km and is 3,3 richter , and two others that were similar 0,4 km depth and was 2,9 richter, and one at the same time at 1,1 km depth and that one was 2,1 richte.


Should be interesting what happens the next few hours.

reply to post by Spacedman13


WOW!!!!

After reading you earlier posts about the historical activity there, I would have to say that this really should be closely watched.

The 3.3 was really close to the surface. It looks like that specifc area of Hamarinn started off today with this one which was deeper at 9.4 km and a mag of 2.5:
Monday
04.10.2010 05:16:38 64.508 -17.702 9.4 km 2.5 99.0 5.7 km ENE of Hamarinn

Even though that region was active the rest of the day, that specifc area didn't have anything until later in the day which was more shallow at 3.4 km.
Monday
04.10.2010 17:02:01 64.502 -17.817 3.4 km 1.9 90.01 1.7 km NNW of Hamarinn

Then two hours later we get a mag 2.4 that is even closer to the surface at 2.5 km.
Monday
04.10.2010 19:55:53 64.545 -18.074 2.5 km 2.4 88.44 14.2 km WNW of Hamarinn

Several hours later and we have the 'big' one close to the surface.
Monday
04.10.2010 23:38:19 64.509 -17.749 0.8 km 3.3 90.09 3.8 km NE of Hamarinn

And now the eq activity for that specific Hamarinn area is going deeper again at 4.9 km with a 2.2.
Monday
04.10.2010 23:49:19 64.502 -17.761 4.9 km 2.2 68.47 2.9 km NE of Hamarinn

So deep, then close to the surface, and now going back down.

That's definitely odd!!!!

Edit to add: Two more just went off while I was writing the above post. It went deeper again...to 8.1 km...and then just a few minutes later, back up to 3.7 km.

Tuesday
05.10.2010 00:33:12 64.474 -17.697 3.7 km 2.2 64.85 5.6 km ESE of Hamarinn
Tuesday
05.10.2010 00:27:33 64.503 -17.689 8.1 km 2.3 52.48 6.0 km ENE of Hamarinn

I was looking at the Hengill region quakes that happent in 2000, it was such amount of quakes in one region that i still find it quite alarming.Below are pic´s from 5 weeks of quakes.

Week 24
[atsimg]http://files.abovetopsecret.com/images/member/2fc61c6f2883.gif[/atsimg]

Week 25
[atsimg]http://files.abovetopsecret.com/images/member/5b122b994435.gif[/atsimg]

Week 26
[atsimg]http://files.abovetopsecret.com/images/member/16a25782e0bc.gif[/atsimg]

Week 27
[atsimg]http://files.abovetopsecret.com/images/member/ce187d1440fb.gif[/atsimg]

Week 28 Notice the quake next to Hekla the one that´s over 4 richter
[atsimg]http://files.abovetopsecret.com/images/member/9f33f7d2a669.gif[/atsimg]

Once i saw the quake that was next to Hekla i rememberd that there was a eruption in 2000, so i looked into it and noticed that this happent.

Week 8. Hekla erupted. Notice the amount of activity in the Hengill region.
[atsimg]http://files.abovetopsecret.com/images/member/569e7419e075.gif[/atsimg]

Hekla erupted and 3 months later the hengill region went berserk. Im thinking there´s a clear link inbetween there, if Hekla erupted cousing tension release on the chambers below it could have coused the activity that followd those 3 months later. And also if you look at the quake activity at Mýrdalsjökull and Torfajökull before the Hekla eruption you´ll notice a wery similar behavior as we are having today. 5-30 quakes at Mýrdalsjökull and 1-3 minor quakes near Torfajökull.

This is all wery wery interesting.........

reply to post by Spacedman13


It is wery wery interesting.

Since all of the activity yesterday, there has only been three more eq's in that area so far today, with two of them at Bardarbunga, and neither as shallow as the majority of them yesterday. The other one was at Kverkfjöll, which also saw a few eq's yesterday at varying depths.

Tuesday
05.10.2010 04:51:34 64.629 -17.400 8.7 km 2.3 99.0 6.2 km E of Bárðarbunga
Tuesday
05.10.2010 03:59:58 64.696 -17.339 9.5 km 1.6 99.0 10.9 km NE of Bárðarbunga

Found a old video from that shows an eruption in the 70' here in iceland on the island Heimey. Just had to post it
only becouse it´s problebly the only volcano stopped by people. Pretty sure the the writers from the movie Volcano with tommy lee jones ripped the idea from us



And a old clip of the forming of Surtsey in the late 60´



I also found this video of a guy who flyes over the country taking vids and pics of places,, this is from the Laki area.



And this is from Mývatn.. trully amazing video´s

You need to go have a look at this. Is Esjufjoll starting to play up?

www.abovetopsecret.com...

Saw this too this Morning PuterMan.
First time I see activity there, under Vatnajokull.

I checked the tremor graph a bit south around that place but didn't see anything unusual on it.

hraun.vedur.is...

same goes for the grf graph n-w of the place where this "swarm" is occuring

hraun.vedur.is...


Still worth keeping a look at this stuff through the week-end.

Nidwin
Iceland, the ATS bros and sistas still watching you. ;-)

TREMOR plots are going crazy at the moment!
