Magnitude-7.2 Alaska quake leads to now-cancelled tsunami advisories along west coast
An overnight earthquake in Alaska set off tsunami advisories but it turned out there was no threat to British Columbia.
The National Tsunami Warning Center in Palmer, Alaska, first notified of the quake shortly after midnight Pacific time. That bulletin was followed about 45 minutes later with the assurance no tsunami was expected.
The tremor was estimated at magnitude 7.2 and struck about 85 km southwest of Sand Point in Alaska, nearly 1,000 km southwest of Anchorage, at a depth of 21 km, at about 11:48 p.m. PT.
There was a tsunami advisory for south Alaska and the Alaskan Peninsula, on the Pacific coasts from Chignik Bay to Unimak Pass, about 130 kilometres northeast of the city of Unalaska.
There was no threat to any other U.S. or Canadian coastlines, according to the update.
