A powerful earthquake hit Alaska overnight, prompting a tsunami warning for coastal areas of Alaska and British Columbia from Attu, Alaska, to the Washington State border.

A tsunami watch was in effect along the west coast from Washington to southern California. The U.S. Geological Survey said the quake was a magnitude 7.9. Initial reports said it was an 8.2 magnitude.

All alerts related to the tsunami have expired, according to the National Weather Service National Tsunami Center.

The earthquake hit about 175 miles southeast of Kodiak City, Alaska.

“If you are located in this coastal area, move inland to higher ground. Tsunami warnings mean that a tsunami with significant inundation is possible or is already occurring,” according to an alert from the Anchorage Office of Emergency Management sent after the earthquake.

Hawaii was also under a tsunami watch, although that alert has also been canceled.

The Kodiak Police Department posted a video urging residents to get at least 100 feet about sea level:
