It seems that the eruption in Grímsvötn is quickly winding down.
Plenty of ash to deal with though !
Couple of satellite images, from NASA MODIS sensors, from 23 and 24 May 2011.
23 May 2011. A lot of ash, probably mostly windblown but hard to tell exactly.
24 May 2011. A little better, in terms of actually seeing down to the land surface, and less material being emitted and/or blown.
Measurements in the great Reykjavik area, at Hvaleyrarholti and Digranesheiði, show clearly that as from the eruption in Grímsvötn has reached Reykjavik. Around 20:30 on 22 May 2011.
Latest measurements indicate that this was about the top values, this time around, with concentration much lower now at 22:00, and high value of 194 micro-g/m3 at HEH.
Of course we can expect other peaks like this, even later tonight.
At 13:00 today, 22 May 2011 (NASA MODIS/Rapidfire).
Today at 11:26; 22 May 2011 (MODIS/NASA/RAPIDFIRE – EV).
Today at 13:04 (MODIS/NASA/Rapidfire).
Eruption has started in Grímsvötn, Vatnajökull, Iceland.
Big plume, and some ash fall. Can expect jökulhlaup, probably not very large, but depends on the size of the eruption site.
