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 2301-m-high summit is truncated by a horseshoe-shaped crater breached to the west that formed about 8000 BP during an eruption producing a directed blast and a 3 cu km debris avalanche that traveled 19 km west. Another strong explosive eruption took place about 2500 BP. Two satellitic cones occupy the southern flank, and a cluster of Holocene cinder cones farther to the south may also be related to Taunshits.

The western side of Taunshits, a large stratovolcano located west of the massive Uzon caldera, is breached by a large horseshoe-shaped caldera. The caldera truncates the volcano from its summit to its base and was formed about 8000 years ago during an eruption that produced a debris avalanche and directed blast similar to that at Mount St. Helens in 1980. A viscous lava flow (center) erupted after the collapse and descended across the breached caldera from a vent at the head of the collapse scarp.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
