A plume rises above Ontake, the summit crater of Suwanosejima volcano. The 8-km-long island of Suwanosejima 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 crater that opens towards the sea on the E flank. The horseshoe-shaped crater formed by edifice collapse. This one of Japan's most frequently active volcanoes and has been in a state of intermittent Strombolian activity since 1949. Photo by Yukio Hayakawa, 1998 (Gunma University).
