Tao-Rusyr Caldera is a stratovolcano located at the southern end of Onekotan Island, Kuril Islands, Russia. It has 7.5 km wide caldera formed during a catastrophic eruption less than 10,000 years ago (reported ages range from 5550 to 9400 Before Present). The waters of Kal'tsevoe Lake fill the caldera, along with a large symmetrical andesitic cone, Krenitsyn Peak, that rises as an island within the lake. The most recent eruption, in 1952, formed a small lava dome on the island's coast. Krenitsyn Peak has a summit crater 350 m wide and is the highest point of the volcano and on the entire Onekotan Island. Another caldera, Nemo Peak, lies at the northern end of the island, and it also contains a central cone and crater lake.
