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 major earthquakes occurred in 1952; 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, causing a major tsunami. This event was the largest and deadliest of the year; it was also one of the largest of all time.

Information on the disaster was sparse due to secrecy by the Soviet Union government. Estimated death tolls for the tsunami range from 4,000 to as much as 17,000. Major damage was caused in the area. Hawaii saw some damage from the waves. Many aftershocks followed but to prevent cluttering only magnitude 6.5 or greater ones are included. | 4,000 | |
