List of earthquakes in 1952

This is a list of earthquakes in 1952. Only magnitude 6.0 or greater earthquakes appear on the list. Lower magnitude events are included if they have caused death, injury or damage. Events which occurred in remote areas will be excluded from the list as they wouldn't have generated significant media interest. All dates are listed according to UTC time. Two events dominated 1952 in seismic terms. Firstly in March a magnitude 8.1 earthquake struck Japan resulting in a robust aftershock sequence. Then in November, a magnitude 9.0 earthquake rocked the Kamchatka area of Russia. This event was the largest and deadliest of the year. The Kamchatka quake was not only the largest of 1952, but also one of the largest of all time.

  • A magnitude 9.0 earthquake struck off the east coast of Kamchatka, Russia on November 4 at a depth of 21.6 km. This was one of the largest earthquakes of all time. This event triggered a devastating tsunami. The death toll varied from a low estimate of 4,000 to as high as 10-17,000. Information on the disaster was initially sparse due to secrecy by the government of the Soviet Union.[119][120][121]
