The 1989 Ungava earthquake occurred at 09:24 local time (14:24 UTC) on 25 December to the north of Lac Bécard in a remote part of the Ungava Peninsula in northern Quebec. It had a magnitude of 6.3 on the surface-wave magnitude scale and 6.2–6.5 on the moment magnitude scale and a maximum felt intensity of only IV (Light) on the Mercalli intensity scale, due to its remoteness from any inhabited areas. The mainshock was preceded by a magnitude 5.1 foreshock ten hours earlier. It was the first earthquake in eastern North America known to be associated with ground rupture.
