Ksudach Volcano - John Seach
(Voniuchi Khrebet)
Kamchatka, Russia
51.80 N, 157.53 E
summit elevation 1079 m
shield volcano
The volcano is located in southern Kamchatka.
The summit contains two lakes - Balshoe and Kraternoe.
The volcano consists of nested calderas which formed during five collapse events.
Two larger calderas formed in the Late Pleistocene time and three smaller ones during the Holocene.
A large eruption in 1907 from Stubel Crater produced ashfall deposits 200 km from the volcano. Pyroclastic deposits of the largest Holocene eruptions are tens to hundreds of meters thick near the vent.
An eruption of Ksudach in 240 AD was the second largest in Kamchatka during the past 10,000 years.
