A shot from the Hekla webcam showing the glow from the eruption of Eyjafjallajökull that started March 20, 2010.

Quick note, but for those of you who have been following the seismicity at Eyjafjallajökull in Iceland, there is news from Iceland that an eruption has started. I will post more details as I can find them, but so far, evacuations have commenced near the volcano. It sounds like the eruption can be seen coming through the glacier on the volcano, but any real details of the style of volcanism are unknown. This is the first known eruption of Eyjafjallajökull since 1823.

UPDATE 9:40 PM EDT 3/20/2010: Here is some more news, but in Icelandic. It appears that at least 500-600 people living near the volcano will need to be evacuated.

UPDATE 9:45 PM EDT 3/20/2010: Here is information released warning pilots of the eruption. There are also second-hand reports of ash fall near the glacier on the volcano. Thanks to Damon Hynes for this info.

UPDATE 9:55 PM EDT 3/20/2010: More news, translated through Google. Ash has been reported and this article has a picture from the Hekla webcam showing the glow from the eruption.

UPDATE 11:25PM EDT 3/20/2010: Here is an update on the eruption from the BBC.
