Volcán Ksudach

Ksudach

Estratovolcán · Russia · 1007 m

Ksudach, the large volcano seen here from the SW, contains five calderas with the northern of two caldera lakes (center) forming an embayment in Shtyubel' Crater. Situated within the youngest caldera, Ksudach V, Shtyubel’ has been active since about 1,600 years ago and an eruption in 1907 was one of Kamchatka's largest in historical time.

Resumen geológico

Ksudach is unique among Kamchatka volcanoes in its morphology and geologic history. It is a large, low-angle stratovolcano, constructed of alternating basaltic-andesitic lavas and dacitic pyroclastics, and is truncated by an intricate complex of five calderas. An array of post-caldera structures is truncated by later calderas, the last three of which formed during the Holocene, about 7,900 and 5,000 BCE and about 240 CE. The latter eruption was the second largest in Kamchatka during the Holocene, and produced about 20 km3 of rhyodacitic airfall tephra and 3-4 km3 of pyroclastic flows. The eastern part of the caldera complex contains two lakes, the northern of which forms an embayment in Shtyubel' (Stubel) Crater, a low-angle cone that began forming about 1,600 years ago in the youngest caldera. The only historical eruption, in 1907, originated from Shtyubel'.
