Volcanos in Iceland, possible alarm?

reply to post by jazz10


We do not get alot of hail here in Iceland , there´s alot of snow during the winter but hardly ever hail. What underground Volcano´s are you speaking off ? if you are referring to the Tjörnes fracture zone up north off the country i would have to say it is quite active at the moment. I would have to say that area has been the most active region of the country this whole summer with quite a few quakes well over 3 on richter. There have been a few quakes also on the fracture line north and south of the country, i can at least remember 2 quakes that were over 5 richter , each on each side of the country. You can find the latest information about anything happening from www.abovetopsecret.com... this thread has all the Volcano, quakes and other interesting forums speaking about what is happening at the moment in the world.
to Puterman to putting all those sites and forums together

Having a hard time getting my hands on my pic´s from my vacation, somehow my mother had them and uploaded them on my sisters pc, my sister is checking to see if they have them so im just waiting on it. But there was one pic uploaded on facebook that i just copied. This is one of 3 craters that are side by side but this is the most popular one becouse of the size of it and how it looks. One of the most popular siteseing stops for tourists here in Iceland.

Trully hope i can get my hands on those pic´s becouse this picture hardly shows the size of this crater and i have pictures of the craters next to it also.


There are two theory´s regarding these craters, one is that this was a explosive crater that burst up and created this crater and the other is that this was a small volcano that collapsed on itself. But seing as there are 2 craters next to it that look pretty mutch the same, i would have to rule out the 2nd theory as i can imagine one volcano collapsing on itself but 3 all next to each other.

Amazing picture!

Thanks for sharing that for sure!

This area of Grímsvötn is looking more and more active. Even had a 3.0 eq this morning.

The eruptions blog mentioned it yesterday as well. Any thoughts:

Well i notice they lowerd it down to a 2,3 wich they have been doing alot with the larger quakes this summer, there is a volcano in the center of Vatnajökull called Esjufjöll it is suposed to be 4times the size of Katla´s crater. But it has not erupted in our times so they hardly acknowlige it. Bárdabunga has been quite active the last month and half died down a wee bit last week but it´s back to the status it was in. This is the most activity for the middle of Vatnajökull all summer, there have been 2-3 quakes about 3-4 times this summer, we´ll just have to wait and see if it the area keeps shaking a bit or if it´s just the same as this summer. Couple of quakes then nothing.

Hey, thank you for that update!

It is hard to really understand the complex nature of the volcanos in iceland. Thanks

It´s mother nature, there´s alot to understand but all we can do is watch the show

I see a cluster on Katla right now.

hmmmmmm. think it's gonna blow?

5 quakes in total there, i really doubt it. But good guess though, one never knows

That same area is still moving around a bit and at varying depths.

Worse than that now. There has been a 3.5 and 3.9 almost on top of each other just by Grimsvotn.

This is iceland quakes over 3.5 (I think that is around the EMSC limit as they don't go below 3.4) for the past 7 days.

It does seem to be little bit above the 'norm', right? I've only been watching this area since the Eyjafjallajökull eruption earlier this year, so I do not have any real historical idea of the activity here. But I do know that I have not seen this level of activity in this area since Eyjafjallajökull's show.

20 EQ's in the same area so far today.

In my opinion, and think I have stated this on this thread, or if not on the Volcano or Quake watch threads, this area and Hekla are much more areas to watch than Katla. For one thing the volcanoes of the Vatnajokull glacier and the associated fracture zones (Laki etc) have been responsible for the largest amounts of destruction, and so to a degree has Hekla in its history. This is not belittling Katla which has had it's moments. I just think the others more worthy of attention.

The 5.2 and 5.4 may be the same event. I am checking on that.

Just been a 5.0 as well.

Interesting how the Reykjanes Ridge makes a direct bee line all the way up to Iceland. I wonder to what degree, if any, moderate size quakes on this ridge (like these 5's) could affect those volcanoes...

That same area has calmed down a bit today, but there were 41 quakes there between Saturday and Sunday, plus the larger ones on the fault line off the coast:

Does anyone have any links to more cams in Iceland?

I still have all of the Eyjafjallajökull cams, and ones for Hekla and Katla also, but I am looking for cams and/or more seismic info in the Vatnajökull region. Thanks in advance!

This is about as good as it gets on GPS. Takes you to day 70 or so (bear in mind we are at day 270)

GFUM (Grimsfjall)

No cameras, no other seismic info other than that we already have. The only other information I can get hold of is out of date, i.e. not current to today.

Now is that my imagination or are we seeing continual uplift on the vertical (UP) axis?

I came across this little bit of info today:

VatnajĂśkull glacier

Two earthquakes occurred late on Saturday night by Hamarinn at the northwestern part Vatnajökull glacier in Iceland’s highlands. The first quake, measuring 3.5 on the Richter scale, hit at 9:11 pm and the latter, which measured 3.7 in strength, around 11:30 pm. Geophysicist Páll Einarsson told Morgunbladid that it is not unusual for series of earthquakes to hit the region; a time of unrest is beginning in Vatnajökull. However, the series is not directly related to the volcanic lakes Grímsvötn and they cannot be categorized as volcanic unrest, Einarsson said. Yet Einarsson stated in a recent presentation that an eruption in Grímsvötn is highly likely within the next months.

The rest of the info can be found here.

Iceland is a very interesting place.
