The 1797 Sumatra earthquake occurred at 22:00 local time on 10 February.[1] It was the first in a series of great earthquakes that ruptured part of the Sumatran segment of the Sunda megathrust. It caused a damaging tsunami that was particularly severe near Padang, where a 150–200 t (170–220 short tons) English ship was driven 1 km (0.62 mi) inland up the Arau River.
