Krenicyn

Tao-Rusyr Caldera

Stratovulcano · Russia · 1272 m

Krenitzyn Peak is a post-caldera cone that forms a 4-km island rising above the rim of 7.5-km-wide Tao-Rusyr caldera. It has a 350 m summit crater and a large shallow crater (left center) on the upper NE flank. The small dark mass along the eastern shoreline (right-center) is a lava dome that was emplaced in 1952. Kal'tsevoe lake fills a caldera that formed about 7,500 years ago during one of the largest Holocene eruptions in the Kuril Islands.

Sintesi geologica

The southern half of Onekotan Island in the northern Kuril Islands contains the 7.5-km-wide Tao-Rusyr caldera, which is mostly filled by Kal'tsevoe lake. The basaltic-to-andesitic caldera formed about 7,500 years ago, in which the large post-caldera Krenitsyn Peak grew, building a 4-km-wide island in the NW part of the lake that rises above the caldera rim. A 350-m-wide, 100-m-deep crater truncates the peak, and a large crater is located on the upper NE side. An eruption in 1952 formed a small lava dome in an explosion crater along the eastern shore of the island.
