A 7.5-magnitude earthquake struck off the coast of Alaska near midnight on Friday, the U.S. Geological Survey said, prompting tsunami warnings and advisories down the coast of Alaska and Canada's British Columbia.
All tsunami warnings, watches and advisories were later canceled, the West Coast and Alaska Tsunami Warning Center (of the National Oceanic and Atmospheric Administration) said.
The quake struck in the Pacific Ocean about 60 miles southwest of Port Alexander, Alaska, at a depth of about 6 miles at 11:58 p.m. local time (3:58 a.m. ET), the USGS said.
Initially, the USGS reported that the temblor had a magnitude of 7.7, but it later downgraded the quake's strength to 7.5.
A 6-inch rise in sea level was reported in Port Alexander, but there were no early reports of damage.
A tsunami warning was issued for the coastal areas of British Columbia from the north tip of Vancouver Island to Cape Suckling, but it was later canceled.
