Photo Gallery


Ichinsky is the highest peak in Kamchatka's Sredinny Range, which extends along the western side of the peninsula. The 3621-m-high summit cone of the massive stratovolcano, seen here from the south, was constructed within a 3 x 5 km-wide glacier-covered caldera. A dozen late-Pleistocene to Holocene dacitic and rhyodacitic lava domes circle the peak below the caldera rim, at elevations of 1800-3000 m. Fumarolic activity occurs within the caldera and on the lower northern flank.

The setting sun gilds the SW flank of Ichinsky, the most prominent volcano of the Sredinny Range. Two glacier-covered lava domes form the summit of the volcano. The massive stratovolcano is one of the largest volume volcanoes in Kamchatka. No historical eruptions are known from Ichinsky, but Holocene eruptions have produced dactic-to-rhyodacitic lava domes and voluminous basaltic-to-andesitic lava flows from flank vents.
