What the record says

NCEI’s account, from the sources it cites.

Mallet (Reference #496) reported that several severe shocks occurred and, "The sea rose to the heigh of 10 feet at a half-a-mile from its ordinary beach and swept away a number of houses." Mallet surmised that this is likely the same event, misdated, as October 2, 1780.
