Ground shaking was strongest in Sand Point, with reports of "objects flying out of the pantry and off of shelves," noted the Alaska Earthquake Center.

The giant earthquake was recorded at 12:37 p.m. local time, southeast of Sand Point, a community located on Popof Island in the Aleutian Chain.

The quake that struck Alaska’s southern coast on Wednesday, July 16 is part of a larger sequence that may continue to unfold in destructive ways.

The National Weather Service has lifted a tsunami advisory for communities on the Alaska Peninsula and Kodiak Island after a magnitude 7.3 earthquake struck about 55 miles south of Sand Point. The advisory was lifted at 2:43 p.m. Wednesday.

A tsunami warning that was later downgraded was issued for several coastal communities after the earthquake struck south of Sand Point.

The warning includes the southern end of the Alaska Peninsula, along the coast, and up to both sides of Cook Inlet.

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.
