(CNN) -- 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.
