Two Kamchatka earthquakes, which occurred at approximately the same location off the coast of Kamchatka Peninsula in far eastern Russia on October 16, 1737 and November 4, 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 7000–7500 meters. Northern Kamchatka lies at the western end o...

Two Kamchatka earthquakes, which occurred at approximately the same location off the coast of Kamchatka Peninsula in far eastern Russia on October 16, 1737 and November 4, 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 7000–7500 meters. Northern Kamchatka lies at the western end of the Bering fault, between the Pacific Plate and North American Plate.
The epicentre of the 1737 earthquake was located at 52.5°N and 159.5°E. This earthquake occurred at a depth of 40 km. A magnitude of 8.3 Ms has been estimated.
The main earthquake struck at 16:58 GMT (04:58 local time) on November 4, 1952. Initially assigned a magnitude of 8.2, the quake was revised to 9.0 Mw in later years. A series of tsunami resulted, causing destruction and loss of life around the Kamchatka peninsula and the Kuril Islands. Hawaii was also struck, with...
