Tsunami warning after 7.7 earthquake off Haida Gwaii (Queen Charlotte Islands)
A tsunami warning is in effect for coastal areas of British Columbia and Alaska from the north tip of Vancouver Island to Cape Decision, Alaska (85 miles southeast of Sitka).
This follows a 7.7-magnitude earthquake off Haida Gwaii at 8:04 p.m. It's listed at 7.1 on the Natural Resources Canada website.
However, the widely respected U.S. Geological Survey has it listed as a 7.7. quake on its website. It also reports aftershocks of 5.8, 5.1, and 4.8 in the 81 minutes after the original earthquake.
Tsunami warnings mean that widespread dangerous coastal flooding along with strong currents may last for several hours after the initial wave arrival.
The Emergency Info BC website states that a warning "means that a tsunami is expected and imminent in low-lying coastal areas".
"People in these areas must move inland or to higher ground IMMEDIATELY," the site states. "Do not return until directed to do so by local emergency officials. A tsunami is a series of waves and the first wave is not usually the largest and could last several hours."
People in Tofino have been ordered to leave their homes and head to the local community centre.
Earthquakes are not uncommon in this area.
