The warning area extended for about 764km, stretching from 120km southeast of Cordova, Alaska to the north tip of Vancouver Island, Canada.

The powerful quake did generate a small tsunami, but the Alaska Tsunami Warning Center (ATWC)  said the waves didn’t pose a threat.

ATWC canceled the warning at about 2 a.m on Saturday.

The temblor, which was 9.8km, hit off the coast of Alaska 102km west of Craig, a town on Prince of Wales Island, and 335km south of the capital of Juneau, the U.S. Geological Survey said.

There were no immediate reports of casualties or damage from the earthquake.
