The Atka volcanic complex at the NE tip of Atka Island is one of the largest volcanic centers in the central Aleutians. It contains a caldera and is surrounded by 7 or 8 smaller cones. This view from the south near Atka village shows Korovin, the highest and northernmost of three Holocene cones of the Atka complex.

This view from the NE in June 1986 shows steam rising from the summit crater of Korovin, north of Atka. It has been reported to have a cylindrical vent of greatly variable depth depending on the presence of a lake.

A gas-and-steam plume, possibly containing minor amounts of ash, rises above the summit of Korovin volcano on 4 March 1987. This view of Korovin, north of Atka, was taken from the south. A satellite image on 18 March showed three distinct plumes originating from Korovin and two vents to the south.

Korovin is seen here from the S, with the smaller Konia cone on its SE flank. Korovin is one of the most frequently active centers of the large complex at the NE tip of Atka Island, and contains two craters near the summit. The SE cone has a 1-km-wide crater, larger than the NW summit.

A satellite image on 4 July 2004 showed fresh ash deposits on the upper E flank of Korovin. This photo, taken from the SE, show ash emplaced on the upper slopes of the SE crater.

Photo by Game McGimsey, 2004 (Alaska Volcano Observatory, U.S. Geological Survey).
This photo taken on 3 March 2007 shows a light-gray ash deposit on the W flank of Korovin. In late November 2006 satellite images showed a light dusting of ash on the E flank of the main crater along with several plumes and/or their shadows visible along the N side of the crater. On 11 and 21 December 2006 Atka residents again witnessed steam plumes, possibly containing ash on the latter date.
