Hawaii is under a tsunami warning following a massive earthquake that struck central Chile.
The Pacific Tsunami Warning Center also said a tsunami advisory was in effect for the coast of California and an Alaskan coastal island area from Kodiak to Attu.
The center says a tsunami has been generated that could cause damage along coastlines of all islands in the Hawaii. It said a tsunami in California and Alaska was possible.
The Ewa (EH-vah) Beach, Hawaii-based tsunami center says the first waves are expected to arrive at 11:19 a.m. Saturday (4:19 p.m. EST).
The center called for "urgent action to protect lives and property" in Hawaii, which is among 53 nations and territories subject to tsunami warnings.
The largest earthquake ever recorded struck the same area of Chile in 1960. The deadly wave that it caused raced across the Pacific and hit the Hilo area of the Big Island, where 61 people were killed.
