Krasheninnikov Volcano

Krasheninnikov Volcano is an active stratovolcano 1,856 meters high in the Kronotsky Nature Reserve, in the Yelizovsky District of Kamchatka Krai. It lies about 13 kilometers south of Lake Kronotskoye, off the usual tourist trails but not far from Kamchatka's two most famous sights, the Valley of Geysers and the Valley of Death. The reserve's protected status means a strict access regime: there is no way to reach the volcano's foot on one's own, and the whole surrounding area is closed to unsupervised visits.

Caldera and cones

The volcano grew within an elongated caldera about 9 kilometers long, estimated to be around 39,600 years old. Such a caldera forms when an older edifice collapses after a powerful eruption, and a new volcano later grows in its place. Two merged cones rise from Krasheninnikov's caldera. The southern cone carries a crater about 750 meters across and roughly 100 meters deep — comparatively small by Kamchatka standards, but well preserved. The northern cone is more complex: it is built of three younger cones that grew one above the other, giving the summit a stepped silhouette.

Eruption history

The last pre-modern lava eruption of the volcano is dated to 1463, after which it was considered quiet for centuries. In 1963, only signs of fumarolic activity — hot volcanic gas vents without lava, a common sign of a dormant volcano in the region — were observed in the crater of the middle northern cone.

In early August 2025 Krasheninnikov Volcano suddenly woke up: an ash column rose to a height of about 6 kilometers. It was the first historical eruption of the volcano in the last 600 years and one of the notable volcanic events of recent years on Kamchatka. Volcanologists note that the renewed activity threatens the ecosystem of the neighboring Valley of Geysers, home to the peninsula's geysers and thermal springs.

Getting there

Krasheninnikov Volcano sits in a remote part of the Kronotsky Nature Reserve with neither roads nor hiking trails leading to it. Practically the only way to see it is a helicopter tour from Petropavlovsk-Kamchatsky that flies the route Petropavlovsk-Kamchatsky — Valley of Geysers — Krasheninnikov Volcano, combining a view of the volcano with a visit to the geyser field. Visiting the reserve and its surroundings on one's own requires special permission from the Kronotsky Nature Reserve administration.
