There was a pretty spectacular volcanic explosion at Colima in Mexico yesterday. This time-lapse video compresses about four minutes of footage into about 30 seconds. Watch it in full-screen mode for the best results.
That's only the second time I've seen a mountain-top blown away, although this was on a much smaller scale than the previous one - Mount St. Helens in 1980.
I'd as soon be far, far away from those things when they go off . . .
