Quaking Icelandic Volcanos

UPDATE: The original image has left their server, so I’m inserting the slightly later one from the link below, that still exists. I think I saved the original on another computer, so if I can find it, I’ll put it here later.

Iceland Volcano Quake Map

Iceland Volcano Quake Map

Original image with legend and description

Red is a new quake up to 4 hours, Black is the oldest at 36 to 48 hours, in between are Orange 4-12 hours, Yellow 12-24 hours, and Blue at 24-36 hours old.

At the time of this writing, all are below Magnitude 3. The picture above ought to be a static one, we’ll have to wait for the passage of time to find out if they delete them after a while, but the link will be to an active image that will give the present status.

It sure looks like the activity is not restricted to The Volcano No One Can Pronounce and is spreading out to include the bigger neighbor…

Historically, the volcanic system has them both go when they go, but with about a 2 year lag for the big boy. We’ll see, but a bit of speculation would put it as probable this time too. With the quakes showing where the magma chamber is causing crustal stresses, it would mean they are both hot, loaded, and ready to rumble…

    Funny, I’ve been following Iceland here, http://hraun.vedur.is/ja/englishweb/myrjokull.html , and it’s clear, with no recent earthquakes shown.

    Wee bit strange is all.

  2. E.M.Smith says:

    It is odd. I wonder if they had a data outage?

    The link above is updating (if you click on the ‘original image’ link, you get a different map from the one displayed up to, reflecting the passage of time) so I would tend to assume that the one with active data is more likely to be correct and the one with no data is having a dropout of some sort. Especially given that the volcano is doing things…

    For example, this link:

    shows a clear progression of activity from the image above.

    But yes, a ‘wee bit strange’ does kind of capture it..

    Don’t hold your breath. This level of activity has been going on since May when the eruption of Eyjafjallajokkul died down. (of course me saying that will probably cause something to change ;-)

    I’ve been keeping an eye on it because of Katla. In all that time I’ve seen no more than a couple of >mag 3 quakes on the whole island http://en.vedur.is/earthquakes-and-volcanism/earthquakes/atlantic/

    @Chuckles – what now – solar alarmism?

  4. Bruce of Newcastle says:

    I think you also have to keep an eye on the shifting faults. I was watching the Tjörnes fracture zone for a long while as it looked like a submarine eruption might take place off of Grimsey, which would be cool, but I think now it was just movement along those faultlines.

    Also more than half of the Mýrdalsjökull tremors in the last 48 hours have been shallow, <2 km depth, which could be just glacial ice melt effects, given it is summer.

    Fun to watch from afar like me, less fun if you have to live next door.

    @Chuckles: Well, it won’t take long to see if he’s right…

    @Verity: I’m not expecting anything “soon”. This is geology after all… where “right now” can mean “in the next 1000 years” ;-)

    @Bruce of Newcastle: Well, as someone who lives on the edge of a minor supervolcano destruction zone (that is rumbling a little), within a dozen miles or so of two major faults (one overdue for a great quake), and in the likely impact zone of tsunamis from The Cascadia Fault ( that’s on a cycle with the due date ‘now’)… it’s fun to have SOMETHING to watch “from afar”! ;-0

    @Verity, I was doing a quick scan around of news and saw the reference to Piers Corbyn’s predictions mentioning volcanoes etc and popped over here to see E. M. at it as well. So I felt that logically, they belonged together.

    As I understand it, Katla has always started muttering shortly after unpronounceable, with last time in 1918 being a fair biggie. Since Katla is right there under the Myrdalsjokull glacier, that gets my attention.

    That beacon of accuracy and enlightenment Wikip.. casually mentions that the laharic deposits from the glacial flood of the 1918 eruption extended the Icelandic coastline by 3.1 miles. Yessss…..

  7. Verity Jones says:

    @Chuckles, I’d agree – but it was Piers Corbyn’s language that prompted my comment. It reminded me of AGW.

    Yes, keeping an eye on Katla…

    And Anthony picks up the story –

    http://wattsupwiththat.com/2010/07/10/katla-making-noise/#more-21673

    This is starting to become ‘very not good’, ‘double plus ungood’ and several similar phrases that spring to mind.
