The 1952 Severo-Kurilsk earthquake struck off the coast of the Kamchatka Peninsula. The 9.0 Mw earthquake triggered a major tsunami that hit Severo-Kurilsk, Kuril Islands, Sakhalin Oblast, Russian SFSR, USSR, on 4 November 1952 at 16:58 (UTC).[4] This led to the destruction of many settlements in Sakhalin Oblast and Kamchatka Oblast, while the main impact struck the town of Severo-Kurilsk.[citation needed] It was the sixth most powerful earthquake on record, and to date, the most powerful earthquake in Russian history.

Tsunami[edit]

The tsunami was generated 130 kilometers (81 mi) offshore Kamchatka, impacting Severo-Kurilsk with three waves about 15–18 meters (49–59 ft) high.[5] After the earthquake the majority of the Severo-Kurilsk citizens fled to the surrounding hills, where they escaped the first wave. However, most of them returned to the town and were killed by the second wave.[5] According to the authorities, out of a population of 6,000 people, 2,336 died.[1] The survivors were evacuated to continental Russia. The settlement was then rebuilt in another location.[citation needed]

Earthquakes continue to happen in the area, including a M7.5 event that occurred at ~56km depth on 25 March 2020.[6]
