Eyjafjallajökull

Is there anybody in there?
Just nod if you can hear me
Is there anyone home?
-Pink Floyd, "Comfortably Numb" lyrics

At work Monday morning I noticed two co-workers were missing. They had flown to Europe last week for a computer conference. It took a moment to put two-and-two together to realize, oh the volcano. They can not come home with airspace over France and England still closed.

Yesterday Astronomy Picture of the Day featured this photo of the volcano.

BusinessInsider.com had this photo of the ash cloud and an informative article on the volcano's impact.

The Map Room blog has a video graphic showing the spread of the ash cloud. Instead of a nice neat streamer it looks like the plume was caught in a washing machine as swirled around making a mess of everything.

Bottom Line

Why did this volcanic eruption in Iceland create so much ash? On April 14 Eyjafjallajökull opened up a vent under a small glacier. The eruption melted a large amount of glacial ice which poured onto the fresh lava fragmenting it into gritty glass particles that were carried up with the rising steam and ash.
