Gas emission near the 1957 dome; caldera lake

During a 14 January overflight, strong gas emission was observed near the 1957 dome, in the N part of the caldera. A lake occupied the caldera center.

Information Contacts: G. Steinberg, Yuzhno-Sakhalinsk.

Eruptive History

There is data available for 2 confirmed Holocene eruptive periods.

1957 Nov 12 - 1957 Dec 1 Confirmed Eruption Max VEI: 3

Episode 1 | Eruption Episode N end of inner caldera
1957 Nov 12 - 1957 Dec 1 Evidence from Observations: Reported
 Explosive activity in November 1957 ended with the emplacement of a 250-m-diameter lava dome that rises ~40 m above the lake surface in the NW part of the inner caldera, just SW of the previous scoria cone. Most of the previous lake area, from the SE end of the dome extending 1 km to the NW caldera wall, was filled in.

Episode 1 | Eruption Episode N end of inner caldera
1923 ± 8 years - Unknown Evidence from Observations: Reported
 A scoria cone about 250 m in diameter, aerially photographed and sketched by Gorshkov (1958 CAVW, and in Green and Short, 1971) that reportedly grew between 1916 and 1931, formed the end of a peninsula extending into the lake from the NE caldera wall. A small lava dome was also noted within the crater of the cone.
