Details for: Suwanosejima
A steam plume rises above On-take, the summit crater of Suwanose-jima volcano. The 8-km-long, spindle-shaped island of Suwanose-jima consists of a stratovolcano with two historically active summit craters. The dipping escarpment at the top of the photo is the NW wall of a large breached crater that extends to the sea on the east flank. The horseshoe-shaped crater was formed by edifice collapse. Suwanose-jima, one of Japan's most frequently active volcanoes, has been in a state of intermittent strombolian activity since 1949. Photo by Yukio Hayakawa, 1998 (Gunma University).
