What the record says

NCEI’s account, from the sources it cites.

There was a strong earthquake (Nov 18 1646 UTC, 32.6N, 132.1E, 0-20 km depth, magnitude 7.4) with source in Huyga-Nada, about 40 km northeast of Miyazaki. It was felt in a vast zone, including the greater part of Kyushu and Shikoku Islands and in the center of Honshu Island. The tremors were especially intensive (IV-V degrees JMA) on Kyushu Island in the southwestern part of Shikoku Island. The street lights were destroyed or damaged at several places, and the telephone lines were cut in the prefectures of Miyazaki, Oita and Kagoshima, which are close to the source; the residents ran to the streets in panic.

A tsunami 1 m high was observed along the eastern coast of Kyushu Island and the south coast of Shikoku Island.
