The main earthquake struck at 16:58 GMT (04:58 local time) on November
4, 1952. Initially assigned a magnitude of 8.2, the quake was revised
to 9.0 Mw in later years. A large tsunami resulted,
causing destruction and loss of life around the Kamchatka peninsula
and the Kuril Islands. Hawaii was also struck, with estimated damages
of up to US$1 million and livestock losses, but no human casualties
were recorded. Japan reported no casualties or damage. The tsunami
reached as far as Alaska, Chile, and New Zealand.
The hypocentre was located at 52.75°N 159.5°E,
at a depth of 30 km. The length of the subduction zone fracture was
600 km. Aftershocks were recorded in an area of approximately 247,000 km2, at depths of between 40 and 60 km.
A recent analysis of the tsunami runup distribution based on
historical and geological records give some indication as to the slip
distribution of the rupture.

1952 Severo-Kurilsk Tsunami was a major tsunami that hit Severo-Kurilsk, Kuril Islands, Sakhalin Oblast, Russian SFSR, USSR, which occurred on 5 November 1952 at about 5 a.m. It led to the destruction of many settlements in Sakhalin Oblast and Kamchatka Oblast, while the main impact struck the town of Severo-Kurilsk. The tsunami was generated by a major earthquake in the Pacific Ocean, 130 km from the shore of Kamchatka,
with an estimated magnitude of 9.0. There were three waves about 15-18
m high. 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. The third wave was minor. According to the authorities,
out of a population of 6,000 people, 2,336 died.
The remaining survivors were evacuated to continental Russia. The settlement was then rebuilt in another location.
