Alaska’s Mount Redoubt volcano began erupting yesterday, according to the Alaskan Volcano Observatory.

“As of 2:00AM March 23, 2009, AVO has recorded FOUR large explosions at Redoubt volcano,” says the Observatory.

Redoubt has been looking angry since February, but so far there are no reported casualties (AFP, AP). The picture below shows the Redoubt summit crater on 21 March, just hours before the eruptions began.
