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 and Hawaii, 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 the warnings were canceled. South Alaska and the Alaska peninsula were then reduced to an advisory, which has also since been canceled.
Overnight evacuations happened in Kodiak, Alaska. People awoke to tsunami sirens and warnings to get to higher elevations.
"This is not a drill. This is a tsunami warning. Everybody get at least 100 feet above sea level"<br/>
Larry LeDoux, superintendent of the Kodiak Island Borough School District, says schools were open as shelters and estimated there were about 500 people at the high school.
He said sirens go off in the community every week, as a test to make sure they are working.
People in Kodiak noted the water receding in their harbor about a foot.
Deep-ocean buoys had measured some waves cresting at around 32-feet as shock waves propagated across the Pacific Ocean.
Kodiak police posted these instructions to residents to their Facebook page.
The fire chief in Seward, a popular cruise ship port, says there was no panic. Seward fire chief Eddie Athey praised his community for doing "the right thing," calling it "a controlled evacuation" as people left for higher ground or drove along the only road out of the city.
Athey says the quake was gentle, and that it "felt like the washer was off balance." He says he knows of no damage in the community.
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.
