The National Tsunami Warning Center had issued an advisory for the western end of the Aleutian Islands, from Amchitka Pass to Attu.

A strong earthquake along Russia's Kamchatka Peninsula caused the National Weather Service to issue a tsunami advisory for parts of Alaska on Thursday.

A major, 7.8-magnitude earthquake struck in the North Pacific Ocean on Friday, according to the United States Geological Survey. The earthquake prompted a brief tsunami advisory, the second-highest alert level, for some coastal portions of western Alaska, which was lifted about two hours later.

A tsunami advisory has now been cancelled after it was issued for the western Aleutian Islands in Alaska shortly after a large aftershock hit far eastern Russia on Thursday morning, local time. The tremor was rated 7.
