Utbrott i rysk vulkan efter skalvet – första på 600 år

Krasheninnikov (Russian: Крашенинников) is a complex of two overlapping stratovolcanoes inside a large caldera on the eastern coast of Kamchatka Peninsula, Russia. It is located in Kronotsky Nature Reserve to the south of Lake Kronotskoye, and is named after explorer Stepan Krasheninnikov. The tephra from the caldera's forming eruption lies on top of material from an eruption 39,000 years ago. It is believed that the two layers are related. The southern of the two cones was constructed over a 4,500 year period beginning 11,000 years ago. The northern cone formed in the same amount of time, but started forming after the southern cone was complete. Krasheninnikov's first eruption since the 16th century, and its first to be directly observed, began on August 3, 2025, four days after the 2025 Kamchatka earthquake.
