Taunšic

Taunshits volcano, located west of the massive Uzon caldera, is an andesitic stratovolcano that was constructed beginning about 39,000 years before present (BP) on top of a large Pleistocene tuya pedestal. The summit is truncated by an open crater breached to the west that formed about 8,000 BP during an eruption producing a directed blast and a 3 km3 debris avalanche that traveled 19 km W. Another strong explosive eruption took place about 2,500 BP. Two satellitic cones occupy the S flank, and a cluster of Holocene cinder cones farther to the south may also be related to Taunshits.
