Anchorage, AK – A tsunami advisory for the Aleutian Islands was canceled Thursday afternoon after monitoring showed no destructive waves reaching Alaska.

According to the National Tsunami Warning Center (NTWC) in Palmer, the advisory was initially issued following a magnitude 7.8 earthquake near Kamchatka, Russia, earlier in the day. By 2:06 p.m. PDT Thursday, officials confirmed no hazardous tsunami activity had been observed.

“No tsunami danger exists for the U.S. West Coast, British Columbia, or Alaska,” NTWC said in its cancellation notice. The agency added that while the advisory has been lifted, residents should wait for clearance from local emergency officials before re-entering any previously restricted hazard zones.

The cancellation follows similar guidance issued by the Pacific Tsunami Warning Center in Hawaii, which also confirmed no threat across the central Pacific.

Officials continue to stress that coastal residents should remain alert to official alerts in future events, as conditions can change quickly with seismic activity in the Pacific “Ring of Fire.”

This will be the final update from NTWC for this event unless additional data is received.
