The quake struck at 1:31 a.m. PT Tuesday and prompted a tsunami warning for the entire B.C. coast and a tsunami watch for the entire U.S. west coast, the U.S. Tsunami Warning System said. 

The U.S. Geological Survey initially reported the quake's strength at 8.2 early Tuesday and later downgraded that to 7.9 with a depth of 25 kilometres. At least three aftershocks have been reported.

Environment Canada says the tsunami warning covers the Central Coast and Northeast Vancouver Island coast, including Kitimat Bella Coola and Port Hardy

The weather agency says people in coastal areas are at risk and should move to high ground now and heed further instruction from local authorities.

Emergency Info BC, directed by the province's lead agency for disaster management, says there is also a tsunami warning in effect for the Juan de Fuca Strait coast, the outer west coast of Vancouver Island and Haida Gwaii.

The emergency agency for Tofino, B.C. on Vancouver Island tweeted a photo of people gathering in an evacuation centre. Tofino Emergency said the first wave was due to arrive at 3:40 a.m. PT.

"If you're in a threat zone, you want to evacuate inland or for higher ground, or depending on your situation, to a multi-storey building, a higher floor of a multi-storey building," said Mike Gismondi, a meteorologist with Environment Canada in Vancouver.

The U.S. Pacific Tsunami Warning Centre issued a tsunami watch for the state of Hawaii, which was later cancelled.
