Ruh-roh.
Katla is rumbling a bit.
Historically, Katla tends to erupt 1-2 years after any eruption in Eyjafjallajökull.
Katla eruptions are also, historically, very nasty, very dangerous and likely to have wide (continental scale) impacts.
But not always.
Katla is the primary motivator for Iceland's rather excellent Civil Defence System.
Earthquakes in last 48 hours under Mýrdalsjökull.
Definitely something stirring under there.
Will need to keep an eye on that, could go burp.
Or not.

As the three remaining readers may have noticed, I've been a bit too busy to blog for a couple of weeks.
But other blogs go on, and right now, over on SciBling "Eruptions" there is a fascinating live discussion in the comments on the possibility of an imminent eruption in Eyjafjallajökull.…
Series of substantial earthquakes in the Katla caldera,
could be nothing could be sign of an impending eruption
there are multiple, relatively shallow earthquakes taking place now,
several with magnitude of 3+

it is dark, no other evidence yet, eg no…
here we go again...
this is the map of earthquakes in the last 24 hours in Iceland,
kinda lit up there - nice illustration of the mid-atlantic ridge coming up from the south and south-west and bisecting the island
so that little cluster under Vatnajökull, that is Grímsvötn
Grímsvötn is a sub-…

It has been hard to keep up with the flood of news from the Eyjafjallajokull eruption in Iceland. Eruptions readers have done a good job with getting new images, videos and info up as they…
CUT. IT. OUT.
Really, I'm sick and tired of Icelandic volcanism. Put a cork in it. Literally. Or fill it up with unused AOL CDs. I don't care how you do it. But if there's as much as a peep from any of your volcanoes anytime in the next five years, we'll take tugboats and tow your island into the middle of the Pacific. >:(
Hmm, the AOL thing might work, though there´d be a severe coaster shortage
But... which volcano? There are 3-4 that are moving, Katla just seems likely to be the most imminent.
Fortunately the tremours stopped.
Well, for a bit, they started again.
Beautiful almost straight line ascending from ~ 10 km down up to the caldera.
"But... which volcano? There are 3-4 that are moving, Katla just seems likely to be the most imminent."
Just nuke them all from orbit...
Actually, would a small hydrogen bomb exploded several kilometers underground be able to create a channel to relieve pressure and avoid explosive eruptions? Not that I'm advocating that, just curious.
