Sarychev Peak

成層火山 · Russia · 1496m

One of the largest recorded eruptions in the Kuril Islands took place 11-16 June from Sarychev Peak. This NASA Space Shuttle view on 12 June shows an eruption plume that rose to 16-21 km altitude; pyroclastic flows reached the sea and extended the shoreline in some areas. The main explosive phase ended on 16 June, but weak explosions producing ash plumes continued prior to arrival of a field team on 26-28 July, when no eruptive activity was observed.

地質学的概要

Sarychev Peak, one of the most active volcanoes of the Kuril Islands, occupies the NW end of Matua Island in the central Kuriles. The andesitic central cone was constructed within a 3-3.5-km-wide caldera, whose rim is exposed only on the SW side. A dramatic 250-m-wide, very steep-walled crater with a jagged rim caps the volcano. The substantially higher SE rim forms the 1496 m high point of the island. Fresh-looking lava flows, prior to activity in 2009, had descended in all directions, often forming capes along the coast. Much of the lower-angle outer flanks of the volcano are overlain by pyroclastic-flow deposits. Eruptions have been recorded since the 1760s and include both quiet lava effusion and violent explosions. Large eruptions in 1946 and 2009 produced pyroclastic flows that reached the sea.
