Koshelev

Stratovolkan · Russia · 1822 m

Koshelev (upper right) is one of the southernmost active volcanoes on the Kamchatka Peninsula, seen here SW of the Kurile Lake caldera. It contains four main cones constructed along an E-W line over a Pleistocene edifice with the central and highest peak being the youngest. An explosive eruption occurred at the end of the 17th century. Alaid, the northernmost volcano of the Kuril Islands, is the peak on the left horizon.

Ringkasan geologi

Koshelev is at the southern end of the Kamchatka Peninsula, SW of the Pauzhetka volcano-tectonic depression and NW of Kambalny volcano. It is a complex group of four stratovolcanoes constructed along an E-W line over a Pleistocene shield volcano. Central Koshelev stratovolcano, the highest peak of the volcanic massif, is Holocene in age; N- and SE-flank craters have also been active during the Holocene. Gorely, a Holocene cinder cone related to regional basaltic monogenetic volcanicm, is located about 12 km NW. The largest Holocene eruption took place from the eastern cone about 6,500 years ago. An explosive eruption was reported at the end of the 17th century. Major thermal fields are located in the summit crater of Valentin volcano and on the western flanks of west Koshelev volcano.
