NCEI’s account, from the sources it cites.

Reference #414:

On February 10, 1797, at about 22:00 there was an earthquake on the west coast of Sumatra Island. It occurred at latitude 2 degrees north to 2 degrees south of the equator. A tidal wave followed the earthquake. It burst into the river at Padang with great force and inundated the city. After this, the water retreated so far that even the

river bed dried up. This process recurred three times. The settlement of Ajermanis on the coast was flooded and many huts were washed away. About 300 people died. One ship was carried 5.5 km inland. The tsunami was considerable on the Batu Islands as well.

Reference #42:
