Comments for the Tsunami Event

Display listing of nearby tsunami events

There was a very strong earthquake and a moderate tsunami with source on the shelf of the Sea of Japan.

The total losses from the earthquake and tsunami (separate figures for each phenomenon are not available) have been estimated at 80 million dollars; 26 people died and about 450 were injured; about 86,400 people suffered material losses.

The maximum tsunami water height was on the coast of Honshu Island closest to the source, which it reached in 10 minutes. Here, on the 40 km stretch between Shioya and Nezugaseki, the maximum rise of water was 4 m with individual waves up to 6 m. The rise of water was also considerable at Ryotsu, south of the source, on the northern shore of Sado Island, at the top of a bay of triangular shape. The gradual narrowing of the bay caused a rise of water of 3 m at Ryotsu compared with 1-1.5 m at the entrance to the bay.

The rise of water was no more that 1-2 m at other points in Japan. A survey of the effects of the tsunami showed some unusual local intensifications and attenuations of intensity which do not correlate with coastal relief, but were due to the dissipating or concentrating; effect of the underwater relief between the source and the coast. The energy of the tsunami is estimated at 2.5 X 1020 ergs.

The tsunami was registered by practically all tide gauges on the coast of the Sea of Japan, including in the USSR.

In Primor'e and on the southwest of Sakhalin, the oscillations in sea level had a maximal amplitude of 3 to 22 cm. Further north, along the coast of the Tatar Strait, and in the east, beyond the La Perouse Strait, the intensity of the tsunami fell to the level of irregular background long-period oscillations. The most intensive oscillations in sea level on the coast of the USSR occurred at Nakhodka and Vladivostok.

In accordance with the dislocations of the sea bottom, the tsunami began with an ebb tide on the coast of Honshu Island near the focal zone and with a flood tide at all other places.

Reference #150 lists 1,960 houses destroyed, 290 houses burned down.

The tsunami was also observed in Korea, Russia, and American Samoa.
