Onekotan is an uninhabited volcanic island located near the northern end of the Kuril Islands along the Pacific “Ring of Fire.” Onekotan consists of two stratovolcanos connected by a relatively flat isthmus.
Krenitsyn is the prominent caldera at the southern end of the island. The mountain rises from a depth of from 600 to 900 meters, and contains a deep central caldera lake with a diameter of 7 kilometers, called Tao-Rusyr Caldera. The central peak of this “island within the island” is actually the highest point on Onekotan Island
Nemo is the peak to the north. It has two nested subsidiary calderas, with the cone of Nemo Peak rising in the southwest end of the youngest caldera and a crescent-shaped crater lake, named Lake Chernoye, partially filling the northeast part.
