MVP #4 Answer: Sarigan


Sarigan Island in the Marianas – your MVP #4.

I have to hand it to all of you, each time I’ve tried to make the Mystery Volcano Photo a challenge, you beat it with flying colors. The photo is, in fact, of Sarigan in the Mariana Islands (thanks to Dr. Ed Kohut for providing the photo). Eruptions reader Cam got the volcano on the second guess, leaving our current standings at:

Not much is known about Sarigan – it is an island composite volcano in the Mariana Islands. The last few eruptions have produced lava dome and flows, including some that slipped over the rim of the main crater. There are no known historic eruptions of Sarigan, but there is a small pyroclastic cone at the summit, which might suggest it has erupted relatively recently (as in the last few hundred years). The only signs of life at Sarigan were an earthquake swarm in August of 2005.

I have some catching up to do with the volcano news, so look for that later today.

    check out the Mt. Rainier seismoometers. Much busier than I’ve seen before.
