Details for: Izu-Torishima
An August 12, 2002 photo shows an ash plume rising from the summit crater of Tori-shima volcano. The unvegetated cone of Iwo-yama, seen here from the south, was constructed during an eruption in 1939 within a 1.5-km-wide caldera that truncates the eroded flanks of the volcano. The circular, 2.7-km-wide island of Tori-shima is located in the southern Izu Islands. The volcano is also referred to as Izu-Tori-shima to distinguish it from the several other Japanese island volcanoes called Tori-shima ("Bird Island").
