The 1605 Keichō earthquake (Japanese: 慶長地震) occurred at about 20:00 local time on 3 February. It had an estimated magnitude of 7.9 on the surface-wave magnitude scale and triggered a devastating tsunami that resulted in thousands of deaths in the Nankai and Tōkai regions of Japan. It is uncertain whether there were two separate earthquakes separated by a short time interval or a single event. It is referred to as a tsunami earthquake, in that the size of the tsunami greatly exceeds that expected from the magnitude of the earthquake.
