Overview

The symmetrical Kronotsky stratovolcano on the Kamchatka Peninsula lies between the Pacific Ocean and Lake Kronotsky. Extensive lava flows on the south side of the volcano dammed the Listvenichnaya River to form the lake. A steep summit ridge forms the peak above flanks that are dissected by radial valleys up to 200 m deep.

Small cinder cones are present on the lower N and S flanks, 5-10 km from the summit. Lavas have been dominantly basaltic, with the exception of the small basaltic andesite summit lava extrusion and a flank lava flow. Fumarolic activity has been reported from near the summit.

Gorbach et al. (2024) found scoria horizons associated with explosive eruptions dated to ~5,200-5,400 and ~6,000 years BP.

Regional Volcanic Activity
The Northwestern Pacific Volcanic Regions contains multiple active volcanic systems. Cross-regional magma interactions and tectonic stresses can influence eruption patterns across the entire arc. Monitor regional seismic activity and volcanic alerts.

About the Photo

Kronotsky stratovolcano Is located between the Pacific Ocean and Lake Kronotsky, Kamchatka's largest lake. The flanks are dissected by radial valleys up to 200 m deep. Weak phreatic eruptions took place during the 20th century. Kronotsky is seen here from the SW with the caldera rim of neighboring Krasheninnikov volcano in the foreground.
