Magnitude 7.7 quake hits off Canada coast

VANCOUVER, British Columbia (AP) – A magnitude 7.7 earthquake struck off the west coast of Canada, but there were no reports of major damage. Residents in parts of British Columbia were evacuated, but the province appeared to escape the biggest quake in Canada since 1949 largely unscathed.

The U.S. Geological Survey said the powerful temblor hit the Queen Charlotte Islands just after 8 p.m. local time Saturday at a depth of about 3 miles (5 kilometers) and was centered 96 miles (155 kilometers) south of Masset, British Columbia. It was felt across a wide area in British Columbia, both on its Pacific islands and on the mainland.

“It looks like the damage and the risk are at a very low level,” said Shirley Bond, British Columbia’s minister responsible for emergency management said. “We’re certainly grateful.”

The Pacific Tsunami Warning Center lifted its tsunami advisory for Hawaii Sunday morning just before 4 a.m. local time, three hours after downgrading from a warning and less than six hours after the waves first hit the islands.

Meanwhile, the National Weather Service canceled tsunami advisories for Canada, Alaska, Washington, Oregon and California.

Tsunami Warning Center officials said wave heights were diminishing in Hawaii, though swimmers and boaters should be careful of strong or unusual currents. The biggest waves – about 5 feet (1.5 meters) high – appeared to hit Maui.

Dennis Sinnott of the Canadian Institute of Ocean Science said a 69-centimeter (27 inch) wave was recorded off Langara Island on the northeast tip of Haida Gwaii, formerly called the Queen Charlotte Islands. The islands are home to about 5,000 people, many of them members of the Haida aboriginal group. Another 55-centimeter (21 inch) wave hit Winter Harbour on the northeast coast of Vancouver Island.

Canada’s largest earthquake since 1700 was an 8.1 magnitude quake on August 22, 1949 off the coast of British Columbia, according to the Canadian government’s Natural Resources website. It occurred on the Queen Charlotte Fault in what the department called Canada’s equivalent of the San Andreas Fault — the boundary between the Pacific and North American plates that runs underwater along the west coast of the Haida Gwaii.

In 1970 a 7.4 magnitude quake struck south of the Haida Gwaii.

The USGS said the temblor shook the waters around British Columbia and was followed by a 5.8 magnitude aftershock after several minutes. Several other aftershocks were reported.
