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.

Communities along a 1,126-kilometre stretch of Alaska's southern coast ordered residents to higher ground after a powerful offshore earthquake Wednesday, but officials quickly downgraded and then cancelled a tsunami warning for the region.

There is no tsunami threat to other parts of the U.S. or Canadian Pacific coasts, including California, Oregon, Washington, and British Columbia.
