WASHINGTON - An earthquake measuring 6.6 struck late Wednesday off Canada's Vancouver island in the Pacific, the US Geological Survey said.
There were no initial reports of casualties or damage.
The quake, which hit at 0310 GMT, was at a depth of 11.4k m (7.1 miles) and 94 km (58 miles) south of Port Hardy, Canada.
The US agency had initially reported a magnitude of 6.7.
The US tsunami warning office in Palmer, Alaska said there was no tsunami danger for potentially affected areas: Alaska, British Columbia, Washington, Oregon and California.
Port Hardy Mayor Bev Parnham said no one in the town was injured but she said "pretty much everyone felt it -- it was quite a shake."
"Our infrastructure is in place and there's no damage that we've been able to see," she said, according to The Vancouver Sun.
