The 1933 Sanriku earthquake occurred on the Sanriku coast of the Tōhoku region of Honshū, Japan on March 2 with a moment magnitude of 8.4. The associated tsunami caused widespread devastation.

Earthquake

The epicenter was located offshore, 290 km east of the city of Kamaishi, Iwate. The main shock occurred at 02:31 AM local time on March 3, 1933 (17:31 UTC March 2, 1933), and measured 8.4 on the moment magnitude scale. It was in approximately the same location as the 1896 Sanriku earthquake and it occurred far enough away from the town that shaking did little damage. Approximately three hours after the main shock there was a magnitude 6.8 aftershock, followed by 76 more aftershocks (with a magnitude of 5.0 or greater) over a period of six months. This was an intraplate event that occurred within the Pacific plate, and the focal mechanism showed normal faulting.

Damage

Although little damage was produced from the shock, the tsunami, which was recorded to reach the height of 28.7 m at Ōfunato, Iwate, caused extensive damage, and destroyed many homes and caused numerous casualties. The tsunami destroyed over 7,000 homes along the northern Japanese coastline, of which over 4,885 were washed away. The tsunami was also recorded in Hawaii with a height of 9.5 ft, and also resulted in slight damage.
