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.

The U.S. Geological Survey described it as a magnitude 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.
