There was a jökulhlaup - wish I could have been there with Vatnamælingar on my old route... - actually there were 2 of them, so far. Only about 1/4-1/3 of the ice cap has melted, it is about 1/4 km thick and several km across.
There are, apparently, 5 active vents inside a 1-2 km caldera, with ash rising to 5-10 km.
Heavy ashfall reported across the east, with ash reaching north-west Norway so far.
I had read that the Icelandic Aviation Authority had contingency plans to divert and close air traffic lanes across the North Atlantic, revised on an hourly basis - they have 300 flight on average in the zone at any given time.
The contingency plans are now active, with some lanes closed and flights diverted around.

looks like Aberdeen will get some soon...
Fortunately, some lone geologist on nightwatch made the call, and evacuations were made, including those of intrepid reporters heading in and wondering tourists not answering their cell phones.
Eruption is now not so much a tourist eruption, but on the small size of medium, so far.
It may not be done yet.
Scibling Eruptions is on it, as before
Lots of cool photos coming out, and webcams are running, though the weather was poor yesterday.

It didn't take long for UK airspace to close.
It's the Cod War all over again. If Gordon Brown promises not to freeze your assets again, will you make it go away?
Nice work, all of my students are sending messages saying they are stuck abroad and can't fly home in time for Monday morning. How they can afford foreign holidays is another matter...
