A tsunami watch that was in effect for the entire West Coast after a M7.9 earthquake occurred off the south coast of Alaska was canceled by the National Weather Service Tuesday. A small tsunami was generated in Alaska.
The cancellation came at 4:18 a.m. The alerts were canceled after more information and analysis allowed scientists to better define the threat.
The quake struck 175 miles southeast of Kodiak in the Gulf of Alaska. It was first recorded as a M8.2 at 1:30 a.m. but was downgraded to a M7.9.
There have been at least 10 aftershocks.
The watch also included coastal British Columbia, but was canceled as well.
Waves could still be high at the Washington coast. They were forecast to start at Neah Bay at 4:55 a.m., Westport at 5:05 a.m. and Port Angeles at 5:30 a.m.
Parts of south and southeast Alaska were under a tsunami warning, but south Alaska and the Alaska peninsula were the only areas under an advisory, which has since been canceled.
Overnight evacuations happened in Kodiak, Alaska. People awoke to warnings to get to higher elevations.
According to the United States Geological Service, the earthquake was the result of strike slip faulting where the Pacific plate is converging with the North American plate.
USGS says over the last 100 years, 11 other earthquakes of magnitude 7 or larger have occurred within 600km of Tuesday’s quake.
