ANCHORAGE, Alaska (AP) — 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.

The U.S. Tsunami Center said the warning was in effect from about 40 miles (64.4 km) southwest of Homer to Unimak Pass, a distance of about 700 miles. Among the larger communities in the area is Kodiak, population 5,200.

Officials in the community of King Cove, which has about 870 residents and is on the south side of the Alaska Peninsula, sent an alert calling on those in the coastal area to move to higher ground.
