Volcanos in Iceland, possible alarm?

reply to post by BobAthome


For the sample I just gave, which is just Monday so far, it is 6.35 km. But that is just for the 14 eq's so far at the time of this posting.

If I have some time later, I'll go back and do it for Sunday and Saturday.

Just went through the most recent 50 eq's on Sunday, and the average depth for those was around 4.48 km.

Well if there are no new fissures, then where is the nearest vent?

Seems too be travelling snake like .

There are usually hundreds of birds here

Where did they go?

Ok what just happent???

Earthquake count:
Magnitude less than 1: 16
Magnitude 1 to 2: 98
Magnitude 2 to 3: 15
Magnitude more than 3: 0
Total: 129

so, am i hallucinating or did 350+ quakes just dissapear of the map. Even now the pics of the area´s are showing the same as the frontpage did yeasterday, this smells a bit more like.

" Everything is Fine come to Iceland , nothing to worry about here What quakes???"


Well seing as the site clearly bugged at the moment, on the frontpage there is the review of the largest quakes in the last 48 hours and it says 20-21 feb.

We´ll have to make due with this report from MBL

Still shiver and shake the ground Krýsuvík, but reportedly Sigþrúðar Ármannsdóttir, land a chemist at the IMO, which measure earthquakes from time to time. "As a result, at half ten last night but went to calm. But there is one and one tremor, and they are all within three points, "he said in an interview with Sigþrúður mbl.is. She said the IMO had not received reports of people met for the earthquake last night and this morning, which could find people in general, small for such mild earthquakes. Numerous earthquakes have been recorded in Krýsuvík area. At just over half nine this morning was the last earthquake recorded at 7:05. "It looks like it is to fade away. But you never know, "said Sigþrúður. Increased Preparedness has been on the IMO for this weekend and last night and it will continue.

Perhaps the phantom quake glitch troubling Yellowstone seismos has migrated to Iceland now but that’s a hell of a lot of quakes they have dropped off the chart

Ok they are changing the graph as we speak , they are clearly going over the quakes.

They are now saying that the 4,1 quake was only a 2,6 which is total B%$%&% we have had quakes in that magnitude before in that region many times and never had it been felt in reykjavík or other regions.

How can quakes in the best moniterd area in Iceland be so way off, not even quakes in the middle of Vatnajökull get lowerd by 1,5 richter.?

Why hide the quake data?
What is going on ?

Overview of the earthquake activity in Krísuvík volcano Posted on February 28, 2011 by Jón Frímann
Today has been interesting in regards to the earthquake activity in Krísuvík volcano. But today there have been well over 800 earthquakes (far as I can tell). Over the past few hours the earthquake activity has slowed down a little bit. But far as I can tell it is far from over and might start to pick up again at any time and with no warning at all.

What´s going on at the MET office, there is no consistency in there reports

Easy Spacebrother ;-)

All data is back now. They had probably a technical issue that made a lot of the quakes go on vacation. JOKE

Let us keep an eye on it although.

reply to post by Spacedman13


Wow so what are they trying to say? That all the data is wrong
Something really fishy is going on if you ask me. Not only in Iceland but I think other places also. I could be wrong but thats the feeling I'm getting.

Here is a map of the North Atlantic.

Earthquake count:
◦Magnitude less than 1: 29
◦Magnitude 1 to 2: 433
◦Magnitude 2 to 3: 87
◦Magnitude more than 3: 5
◦Total: 554

This is todays count

Here is the last one I grabbed yesterday

Earthquake count:
◦Magnitude less than 1: 21
◦Magnitude 1 to 2: 427
◦Magnitude 2 to 3: 87
◦Magnitude more than 3: 6
◦Total: 541

So we have 1 mag +3 removed.

Just thought I would pop this in here

Rainbow!

You realize those pieces of ice are as big as houses and bigger!

Nope,

I think they started to review all the stuff this morning. Don't forget most of the activity happened during the wek-end and I presume the folks where spending Saturday and Sunday with their family and not behind a desk. At least I hope for them.

It's not uncommon to have some quakes being downgrated after being reviewed by a seismologist.

The Icelandic Met Office were having problems with ghost quakes appearing, probably due to the sheer numbers of quakes that came through. What were seeing is them filtering those out.

That is an awesome pic, thanks for sharing that!

You all are definitely right, they are reviewing everything from the weekend. When I was adding up some of the depths last night, I kept a copy of the first 50 eq's from Monday, and all of the depths have been changed, quite a bit in some cases.

I still see that yo-yo going.

Just thought i'd post an update from the Jon Frimann blog.

According to news from Rúv. It appears that hydrothermal areas in Krýsuvík volcano are growing larger following the earthquake swarm in the past few days. This same news also tells that the number of cracks in the ground have grown in numbers following the earthquake swarm, this allows more water to get into contact with the hot rock and that warms the water up fast.

Currently the earthquake swarm in Krýsuvík volcano is quieting down. But that might chance without any warning at all. But won’t be surprised if the earthquake swarm stops completely.

In my personal opinion this is a clue that magma might be pushing it’s way up the Krýsuvík volcano system. I get the clue from the increased hydrothermal activity in the this area. But at the moment it is too early to know for sure if this is going to result in a eruption or not. But if this activity continues as it has then a eruption is going to happen one day. That can also chance without any warning at all. But this type activity means that status of the volcano it self is constantly changing and makes it unpredictable. How eruptions in Krýsuvík volcano behave is also a big unknown.

Interesting to say the least.

Although the swarm appears to be slowing almost to a stop, its still worth watching.

Thanks for the update
I'm absolutely glued to this thread, i find it a wealth of knowledge and learning.

So this volcanic system is unpredictable and how it erupts is an unknown. Should be some interesting times ahead for this area.


It has slowed down quite a bit:

Earthquake count:
◦Magnitude less than 1: 50
◦Magnitude 1 to 2: 445
◦Magnitude 2 to 3: 90
◦Magnitude more than 3: 5
◦Total: 590

Great update!! Thanks for that.

And speaking of updates, the Iceland MET has compeltely changed the depths of every eq from this swarm, they are almost completely shallow now. Hmm?

Also, it does look like it has stopped (crossing fingers here).

Go to sleep now...shhh?

reply to post by boo1981


I agree, although they dont seem too worried, even the locals are still unsure of what to expect.

The coming days should tell us more, there'll be a lot of data to get through still.

A further update from the JF blog.

Update: According to Rúv evening news (Icelandic, video) there appears to be magma related aspect to this weekend earthquake swarm in Krýsuvík volcano. According to Dr. Páll Einarsson geologist at Iceland University it appears that magma is the source (as stated above) of this weekend earthquake swarm. This news also says that there has been a lot of earthquake activity in Krýsuvík volcano over the past two years and this earthquake activity is not only tectonic as is common in this area. The news at Rúv also says that geologist in Iceland are wondering and unsure what exactly is going on at Krýsuvík volcano at the moment. But the reported inflation in the news at Rúv is sad to be 10 cm (I do not know if that number is accurate or not). But it clearly a reason now to watch the activity at Krýsuvík volcano. If there is a eruption in Krýsuvík volcano it is going to be a harmless (as it can be) lava eruption. Unless it is under water, but then there is a Surtsey type of eruption for as long there is water getting into the crater. So don’t expect aircraft problem if there is a eruption in Krýsuvík volcano.

Things just seem to be getting more and more interesting.

A 10cm uplift (if true) is something to watch closely.
