What the record says

NCEI’s account, from the sources it cites.

14:15 local time, referred to as the Luroy 1819 earthquake. This is considered to be the largest known historical earthquake in Fennoscandia. The earthquake was felt "throughout a large district in Norway. Especially at Salten and Helgeland in the province of Nordland" (Reference #1879).

The one large earthquake was followed by several smaller earthquakes (Reference #3957). Reference #1879 says that "the shocks lasted six minutes and were followed by other slight ones at 5 and 7:05 p.m."

Landslides and rock slides occurred, and sediments filled up the bays. It is likely that landslides above or below the water caused the agitation of water that was reported. (Reference #3957)
