6.6 magnitude earthquake strikes off Canada's west coast

With no initial reports of damage or injuries, and no tsunami warning

WASHINGTON: A 6.6 magnitude earthquake struck off  Canada's west coast late Sunday, the US Geological Survey said.

The epicenter of the tremor, which happened at 10:39pm (5:49am GMT Monday), was located about 135 miles (218 kilometers) southwest of Port Hardy - a small municipality on the northeastern tip of British Columbia's Vancouver Island.

There were no initial reports of damage or injuries, and no tsunami warning was issued.

The region is located near the Cascadia subduction zone, a fault line that lies offshore, stretching from northern Vancouver Island to Northern California in the United States.
