The U.S. Geological Survey said a 7.7-magnitude quake struck off the coast of Queen Charlotte Islands in Canada late Saturday. The USGS said the quake had a depth of 10.9 miles.
A tsunami warning was issued for the coastal areas of British Columbia and Alaska – from the north tip of Vancouver Island, British Columbia, to Cape Decision, Alaska.
Such a warning means that all residents in those coastal regions should move immediately inland to higher ground, according to CNN.
