Map of earthquakes occurring in and around Russia since 1900. Most of this seismicity is in the Kamchatka area. Many major earthquakes have occurred in the region of the Kamchatka Peninsula in far eastern Russia. Events in 1737, 1923 and 1952, were megathrust earthquakes and caused tsunamis.
Earthquakes associated with the Kuril-Kamchatka subduction zone are of the megathrust type. The subduction zone is associated with at least two known ~9.0 M w earthquakes in the pre-instrumental period; 1737 and 1841. [6] The 1737 earthquake measured M w 9.0–9.3, and generated the largest known tsunami (60 meters) on the peninsula. [7]
Some of the largest Russian earthquakes since the latter half of the 20th century are the 1958/1963 and 2006/2007 earthquakes in the Kuril Islands near Japan, as well as the 1952/1959 earthquakes in the Kamchatka Peninsula, all of which were ≥ 8.0 M. See also the Kuril–Kamchatka Trench.
The April earthquake was part of a sequence of megathrust earthquakes on the Kamchatka Peninsula, which began in February. On February 3, a magnitude 8.4 earthquake, whose hypocenter was 15 km deep, [9] resulted in extreme shaking assigned XI (Extreme) on the Modified Mercalli intensity scale and caused a tsunami with run-ups of 6 meters.
The 1959 Kamchatka earthquake occurred on May 4 at 19:15 local time with a moment magnitude of 8.0–8.3, and a surface wave magnitude of 8.25. The epicenter was near the Kamchatka Peninsula, Russian SFSR, USSR. Building damage was reported in Petropavlovsk-Kamchatsky.
But the Kamchatka branch of Russia's emergency ministry reported that there was no threat of tsunami and that the recorded aftershocks from the quake ranged in their magnitude from 3.9 to 5.0.
The earthquake was associated with thrust faulting on the subduction zone marked by the Kuril-Kamchatka Trench. Calculation of the earthquake magnitude using tsunami data yielded a moment magnitude of 9.3. [2] Studies of the earthquake has placed the moment magnitude (M w ) of this earthquake at 9.0 to 9.3 and the surface-wave magnitude at 8.3 ...
Northeast of this (off the displayed map) lies Korfa Bay with the town of Tilichiki. On the opposite side is the Shelikhov Gulf. The Kamchatka or Central Range forms the spine of the peninsula. Along the southeast coast runs the Eastern Range (Vostochny). Between these lies the central valley.
