7.5-magnitude earthquake strikes off coast of Alaska; tsunami warning canceled

A tsunami warning was canceled early Saturday for portions of British Columbia, Canada, and southeastern Alaska, officials said. The warning was issued following a 7.5-magnitude earthquake that struck off the coast of Alaska 63 miles west of Craig, a town on Prince of Wales Island, and 208 miles south of the capital of Juneau, the U.S. Geological Survey said. The size of the temblor, which struck at 3:58 a.m. ET, off the coast of Alaska was downgraded by the USGS from 7.7 to 7.5. There were no initial reports of damage but the West Coast and Alaska Tsunami Warning Center said a small tsunami of about six inches was observed near the southeastern Alaskan town of Port Alexander on Baranof Island.
