The warning was in effect for about two hours after the quake struck near southern Alaska.
Parts of Alaska were under a tsunami warning for hours overnight Wednesday after a powerful 8.2-magnitude earthquake struck off the coast.
The earthquake was detected about 75 miles southeast of Chignik, Alaska, said the National Tsunami Warning Center, which issued the warning and lifted it about two hours later.

The warning was in effect for south Alaska and the Alaska Peninsula and the Aleutian Islands, said the center in Palmer, Alaska, which warned that “widespread hazardous tsunami waves are possible,” based on the preliminary parameters of the quake.
Just before midnight local time, a buoy near Sand Point measured a rise in water level of about six inches. Another near Old Harbor on Kodiak Island measured just over eight inches.
A tsunami watch was also briefly issued for Hawaii and canceled a little over an hour later, Gov. David Ige said on Twitter.
In Kodiak, where the earthquake could be felt, tsunami sirens blared and people began moving to higher ground.
Perryville, Alaska, with a population of 113, is 57 miles northwest of the quake’s epicenter, the United States Geological Survey said. Anchorage, with a population of nearly 300,000, was about 500 miles north northeast.
Since 1990, there have been 17 earthquakes of 8.2 magnitude or higher, according to U.S.G.S. data.
