Kronotsky

Stratovolkan · Russia · 3482 m

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.

Ringkasan geologi

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.

Ringkasan Wikipedia

Ringkasan Inggris

Kronotsky is a major stratovolcano on the Kamchatka Peninsula, Russia. It is located in Kronotsky Nature Reserve to the east of Lake Kronotskoye. It has a particularly symmetrical conical shape, comparable to Mount Fuji in Japan and to Mount Mayon in the Philippines. The summit crater is plugged by a volcanic neck, and the summit itself is ice-capped. It exhibits the classic radial drainage pattern, extending downward from its crater. Kronotsky is considered to be one of the most scenic volcanoes in Kamchatka. In the 20th century, the volcano had low activity, with occasional weak phreatic eruptions. Its latest eruption started on October 4, 2025, with an ash cloud up to 9 km (5.6 mi) high.
