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.
Geology
The Kuril-Kamchatka volcanic arc contains more than 60 recently active volcanoes.[2]: 383 The massif of the Krasheninnikov volcano contains two overlapping stratovolcanoes made up of three edifices, with the most recent historic partial cone off the northern cone being called the mid-North cone.[2]: 395 According to the Smithsonian Institution's Global Volcanism Program, the volcano's last eruption before 2025 was dated to 1550 using tephrochronology.[1]
The tephra from the caldera's forming eruption lies on top of material from another volcano's eruption of 39,000 years ago,[2]: 398 and has recently been dated to be 30,000 years old when about 13 km3 (3.1 cu mi) of eruptive volume was deposited up to 200 km (120 mi) to the north.[3]: S45 The southern of the two cones is older and developed over a 4,500-year period beginning 11,000 years ago.[2]: 394 The northern cone which has erupted andesitic lavas and tephra started forming after the southern cone was complete with most being deposited 2200–2400 years ago.[2]: 392 Another sample of Krasheninnikov's eruptive products has proved to be dacite.[1]
Recent activity
The first event to be observed since the 1550 eruption occurred on the 3 August, 2025, just four days after the 2025 Kamchatka Peninsula earthquake. The earthquake is believed to have triggered the eruption, due to the shaking Krasheninikov experienced[4][5][6]
