Myrdalsjokull - is Katla getting ready to rumble again?

This is likely, again, not likely to amount to much, but as Jón Frímann has noted, the Katla volcano in Iceland is getting a bit antsy again. There were a couple of deep quakes nearly two weeks ago and there have been shallower and more numerous quakes since.

These might indicate that magma is making its way upwards. We saw this a few months ago, and it did not amount to anything in the end, but it is a little early to tell yet whether this pattern will be the same, or more serious.

For those who don't know, Katla has often erupted after Eyjafjallajokull, which noticeably erupted back in 2010, shutting down air traffic at the time. And Katla is often the more violent of the two - hence the current interest.

I will update this if it develops into something that may turn out to be more serious.
