Iceland, Eyjafjallajökull - May 1st and 2nd, 2010 from Sean Stiegemeier on Vimeo.
I hadn't seen this until today (courtesy of Edie at The Little Red Tent, and Americablog), but what a beautiful visual of what's happening at Eyjafjallajökull. It's always a shame when natural events cause serious problems for human society, but volcanoes and other geological processes are also a source of wonder. I don't have much else to say, except great job, Sean!
