Kronotsky is seen here beyond Lake Kronotskoye, Kamchatka's largest lake. The lake formed during the late-Pleistocene to early Holocene when a series of voluminous lava flows erupted from the south flank of Kronotsky, damming the Listvenichnaya River. The SE and SW flanks contain scoria cones, and weak phreatic eruptions took place during the 20th century.
