Tsunami Bulletin Issued Following Alaska Quake

A magnitude 8.0 earthquake triggered a tsunami warning for Alaska on Monday, according to a National Weather Service alert.

The quake was located in the Rat Islands, which are part of the Aleutian Island chain. NWS said the deep quake, 114 kilometers, ruled out a tsunami for much of the Pacific Northwest and the Alaskan coast.

“No tsunami threat exists for other coastal areas in the Pacific, although some other areas may experience small non-destructive sea level changes lasting up to several hours,” the alert states.
