Kamchatka earthquakes
Encyclopedia : K : KA : KAM : Kamchatka earthquakes
Kamchatka earthquakes were a pair of megathrust earthquakes occurring off the coast of the Kamchatka Peninsula, in Russia on October 16, 1737, and on November 4, 1952, in the magnitude of ~9.3 and 9.0 respectively, with resulting tsunamis following. Both earthquakes occurred at approximately the same location where the Pacific Plate subducts the Okhotsk Plate at the Kuril-Kamchatka Trench. The depth of the trench at the point of the earthquakes is 7000 - 7500 meters. The epicenter of the 1737 earthquake was located at 52.5°N and 159.5°E. This earthquake occurred at a depth of 40 km. The epicenter of the 1952 earthquake was located at 52.75°N and 159.5°E. This earthquake occurred at a depth of 30 km and the length of the subduction zone fracture was 600 km.
