The U.S. Geological Survey's National Earthquake Information Center says a magnitude 6.6 quake has been recorded in the Pacific Ocean off the northwest corner of British Columbia's Vancouver Island.
There were no immediate reports of damage or injuries. The U.S. National Tsunami Warning Center in Palmer, Alaska, says there is no danger of a tsunami.
The quake hit at 8:10 p.m. local time Wednesday and was centered about 25 miles (40 kilometers) southwest of Port Alice, British Columbia, and about 280 miles (450 kilometers) northwest of Seattle, Washington.
In less than two hours, more than 650 people logged on to the earthquake information site to report feeling the quake.
Port Hardy resident Jennifer Nickerson says the quake caused lights to sway and the fish tank in the hotel where she works to rock.
