Yes, although the seismic activity is still ongoing at a constant and frequent level I was surprised to see the alert level changed to orange. What will happen next I wonder.

There was a 1.7 at - 0.2 km earlier today.


Not too sure what that might imply?.(mabey it could be steam from percolated water?).


But it seems very shallow.

I think most them seem to be to do with magma movement (the harmonic tremor and increased alert level would support this). None of it means that an eruption or one that breaches the ice surface (which is hundreds of metres thick) is imminent but it does suggest that the likelihood of one has had/is increasing.

Dave MacGarvice @subglacial) has a good regularly updated Twitter accoun on recent events and has plotted this morning's quakes v depth on a chart: Originally Posted by: doctormog

I wouldn't give much for any trend analysis on that chart, let alone the straight line shown. Just a lot of small quakes all over, whatever that might mean.

A new intense swarm of quakes in progress, and this lot seem to be a little shallower then the last lot.

For anyone interested Nature has a very good overview of the recent situation and possibilities and why a repeat of Eyjafjallajökull's ash cloud related problems is thought to be unlikely re. recent events in Iceland.

Thanks, good article. It does seem any eruption would not cause problems outside Iceland and there will be no dangerous ash cloud. Wont stop the media scaremongering of course

I had thought the camera at http://baering.github.io/ was updating every minute or so, but I now find that it is actually streaming. I don't know how it is mounted but its interesting to see the camera shake fairly regularly, a big tremor may possibly knock it over.

Yes indeed. I'm keeping an eye on this currently. There have been at least 20 magnitude 2 or greater quakes in the past 45 minutes alone. Something is definitely going on and it will be very interesting to see if or how it manifests itself at the surface.

This video taken yesterday is interesting viewing:

The aviation code has just been updated to red meaning that "Eruption is imminent or in progress - significant emission of ash into the atmosphere likely"

Apparently a small eruption (currently?) has begun:
