Just after the quake, NOAA's National Tsunami Warning Center issued Tsunami Warnings for the immediate Alaska coastline from Kennedy Entrance to Unimak Pass, including all of Kodiak Island, Chignik and Cold Bay. The U.S. Coast Guard reported it evacuated personnel from its base at Kodiak to higher ground and had two air crews stand ready to assist.

A 7.3-magnitude earthquake struck south of Sand Point, Alaska Peninsula, prompting a tsunami warning from NOAA covering the peninsula upto Anchorage. Emergency services urge coastal residents to stay alert and evacuate to higher ground.
