Onekotan is in Russia’s Kuril Islands between Japan and the tip of the Kamchatka Peninsula. The islands were formed by volcanic activity 2 b: }1 z# w2 f! K
caused by the subduction of the Pacific Plate beneath the Eurasian Plate. Subduction can also generate some of the largest earthquakes
on Earth, including a magnitude 9 here in 1952 which was followed a week later by Krenitzyn’s only historical eruption. This image was
