A magnitude-7.7 earthquake has struck off the coast of western Canada and a tsunami warning has been issued. There are no immediate reports of damage.

The U.S. Geological Survey in Colorado says the quake hit the Queen Charlotte Islands at 11:14 p.m. Sunday local time (0314 GMT) and was centered 96 miles south of Masset, British Columbia.

A tsunami warning was issued for coastal areas of Alaska, Northern California, Oregon and Washington state. The U.S. Coast Guard warned everyone with a boat on the water off southern Alaska to take precautions.

The USGS said the 7.7-magnitude earthquake was followed by a 5.8-magnitude aftershock several minutes later.

Lt. Bernard Auth of the Juneau Command Center says the Coast Guard is also working with local authorities to alert people in coastal towns to take precautions
