Data from the Global Volcanism Program of the Smithsonian Institution
Details for: Izu-Torishima
This photo taken on 12 August 2002 shows an ash plume rising from Torishima volcano, a 2.7-km-wide island in the southern Izu Islands. The unvegetated Iwoyama cone, seen here from the south, was constructed during an eruption in 1939 within a 1.5-km-wide caldera. The volcano is also referred to as Izu-Torishima to distinguish it from the several other Japanese island volcanoes called Torishima ("Bird Island").

The circular, 2.7-km-wide island of Izu-Torishima in the southern Izu Islands is capped by an unvegetated summit cone formed during an eruption in 1939. Fresh lava flows from this eruption form part of the northern coastline of the basaltic-to-dacitic edifice. The volcano is referred to as Izu-Torishima to distinguish it from the several other Japanese island volcanoes called Torishima ("Bird Island"). The main cone is truncated by a 1.5-km-wide caldera that contains two central cones, of which Ioyama is the highest. Historical eruptions have also occurred from flank vents near the north coast and offshore submarine vents. A submarine caldera 6-8 km wide lies immediately to the north.
