Communities along a 700-mile stretch of Alaska’s southern coast ordered their residents to higher ground after a powerful earthquake, but officials quickly downgraded and then canceled a tsunami warning in the area.

A lightly populated stretch of Alaska ’s southern coast was under a tsunami warning Wednesday after a strong earthquake was felt throughout the region, and officials in the Pacific Northwest were evaluating whether there was any threat to coastlines there. Early measurements put the quake’s magnitude at 7.3.

A rare tsunami warning was issued for part of Alaska’s coast after a magnitude 7.3 earthquake struck near Sand Point in the Aleutian Islands. A small tsunami wave was measured at Sand Point, Alaska.

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

ANCHORAGE, Alaska ( KTUU /Gray News) - A tsunami warning was issued Wednesday for parts of Southcentral and Southwest Alaska due to a large earthquake along the Aleutian Chain. The quake was measured at a magnitude of 7.3 with an epicenter near Sand Point along the Aleutians, about 83 miles southeast of King Cove.

A magnitude 7.3 earthquake struck Wednesday afternoon just south of the northern Aleutian Islands in Alaska. The epicenter was roughly 600 miles southwest of Anchorage, Alaska. A tsunami warning was in effect for less than an hour, but has since expired with little signs of damage.

A tsunami warning that was issued for Alaska's southern peninsula after a 7.2-magnitude earthquake occurred off the coast was canceled Wednesday evening. The warning has been changed to an advisory and was allowed to expire, according to NBC News.

A tsunami warning has been issued for south Alaska and the Alaska Peninsula after a massive 7.3-magnitude earthquake, according to the National Weather Service.

Cold Bay, Sand Point, and Kodiak in Alaska are in danger from the tsunami, which is likely to hit following a 7.3 earthquake.
