Details for: Korovin

Korovin is seen from the south, with the satellitic cone of Konia on its SE flank to the left of the person at the right. Korovin is the most frequently active volcano of the large volcanic complex at the NE tip of Atka Island, and contains a double summit with two craters located along a NW-SE line. The NW summit has a small crater, but the 1-km-wide crater of the SE cone has an unusual, open cylindrical vent of widely variable depth that sometimes contains a crater lake or a high magma column.
