A huge 7.7 earthquake struck Saturday night off the coast of Northwestern Canada, according to to the United States Geological Survey. The huge Earthquake in British Columbia originated 139km south of Masset, Canada. So far there have been no reports of damage or injuries. The earthquake in Canada was initially reported as a 7.7 magnitude by the USGS and a 7.1 magnitude quake by NOAA, but the latest reports indicate it was indeed a 7.7 event.

The epicenter of the Canada Earthquake was in an isolated area near the Gwaii Haanes National Park Reserve on a small island off Prince Rupert. The location is in the Haida Gwaii  islands (“Islands of the People”), also known as the Queen Charlotte Islands, an archipelago on the North Coast of British Columbia, Canada. A 5.8 magnitude earthquake aftershock was reported in the same area shortly after the initial shock.

A tsunami warning in association with the Canadian earthquake in British Columbia was posted after the event:

A tsunami Warning is now in effect which includes the coastal areas of British Columbia and Alaska from the north tip of Vancouver Island, British Columbia to Cape Decision, Alaska (85 miles SE of Sitka). – Event details: Preliminary magnitude 7.1 (Mwp) earthquake [now revised to 7.7] / Lat: 52.863, Lon: -131.942 at 2012-10-28T03:04:11Z Tsunami warnings mean that a tsunami with significant widespread inundation is expected, or occurring. Warnings indicate that widespread dangerous coastal flooding accompanied by powerful currents is possible and may continue for several hours after the initial wave arrival.

The National Oceanic and Atmospheric Administraion (NOAA) reported the earthquake struke at 8:04 PT on October 27 25 miles south of Sandspit, British Columbia. According to NOAA, earthquakes of this size are known to generate tsunamis. If a tsunami has been generated, NOAA reports the waves will first reach Langara Island, British Columbia at 9:16 PM.

Update: According to a post on The Weather Channel Twitter feed, “no Pacific basin-wide #tsunami threat exists. Local #tsunami warning for northwest BC coast, AK coast SE of Sitka continues.”
