Details for: Kasatochi
A dramatic 750-m-wide crater filled with a salt-water lake truncates the summit of Kasatochi volcano. Steep-sided crater walls rise to a maximum elevation of 314 m above the lake surface, which is less than 60 m above sea level. The volcano is located at the northern end of a shallow submarine ridge trending perpendicular to the Aleutian arc and occupies a small 2.7 x 3.3 km wide island volcano. Reports of activity from the heavily eroded Koniuji volcano to the east probably refer to eruptions from Kasatochi.
