Tao-Rusyr Volcano, Kuril Islands

The Kuril Islands are a volcanic archipelago, stretching 1300 km from Hokkaido, Japan to Kamchatka, Russia. They are part of the Pacific Ring of Fire, the result of subduction of the Pacific Plate under the Okhotsk Plate along the Kuril Trench. At the southern end of Onekotan Island is the Tao-Rusyr Caldera stratovolcano, with its 7500 year old caldera lake. The most recent eruption was in 1952. The smaller Kharimkotan Island to the southwest last erupted in 1933. Collapse of this volcano created a horseshoe-shaped crater, and caused a tsunami that killed two people on a near-by island. The image was acquired June 4, 2012; the enlargement covers an area of 17 by 18.5 km, and is located at 49.3 degrees north, 154.7 degrees east. https://photojournal.jpl.nasa.gov/catalog/PIA24020
