Zavaritzki (Zavaritzky) volcano is a large caldera volcano in central Simushir Island, Kuriles. It is a complex of 3 nested calderas with a central lake (Lake Biryuzovoe). 2 eruptions have occurred at Zavaritzki during the 20th century: a recent lava dome was formed between 1916-1931 and created a small island in the northern part of the lake. The second eruption in 1957 formed a new, 350 m wide and 40 m high lava dome also in the northern part of the lake, which decreased a lot in size. The lava dome extrusion was preceded by explosions.
Note: A volcano with the same name is located in Kamchatka.
