The 1933 Baffin Bay earthquake struck Greenland and the Northwest Territories (now Nunavut), Canada with a moment magnitude of 7.4[1] at 18:21:35 Eastern Time Zone on November 20.

Shaking was only felt at the small town of Upernavik, Greenland.

No damage was reported because of its offshore location and the small population of the nearby onshore communities.

At the location of the earthquake, there is an extinct spreading center which formed the Baffin Bay itself.

Multiple small earthquakes with magnitudes ~4-5.5 still occur each year.
