Where in the World? #4

Last week I had an image of Toba, a volcano on the island of Sumatra in Indonesia (winner: Ron Schott from The Geology Home Companion). Toba had a colossal eruption 70-75,000 years ago which was probably the largest on Earth in the past several million years; even larger than the eruptions of the Yellowstone Caldera (last eruption 640,000 years ago). The volume of material from the Toba eruption was approximately 2800 km3, compared to 1.2 km3 from the 1980 eruption of Mt. St. Helens. The Toba event undoubtedly had a worldwide impact on climate and probably led the the extinction of many species in southern Asia.

This week: one more volcano. What volcano is this?
