Three earthquakes, which occurred off the coast of Kamchatka Peninsula in far eastern Russia in 1737, 1923 and 1952, were megathrust earthquakes and caused tsunamis. They occurred where the Pacific Plate subducts under the Okhotsk Plate at the Kuril-Kamchatka Trench. The depth of the trench at the point of the earthquakes is 7,000–7,500 m. Northern Kamchatka lies at the western end of the Bering fault, between the Pacific Plate and North American Plate, or the Bering plate[2] There are many more earthquakes and tsunamis originating from Kamchatka, of which the most recent was the 1997 Kamchatka earthquake and tsunami originating near the Kronotsky Peninsula.
