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. The caldera forming eruption yielded about of material and destroyed the upper parts of the pre-existing volcano. The event has been potentially identified in the
GISP2 ice core. The caldera forming eruption wiped out vegetation on southern Onekotan, and it took a long time for it to recover. Only one historical eruption occurred at Tao-Rusyr, just after the
1952 Severo-Kurilsk earthquake. Остров Онекотан.
