Tsunami warning issued for southern Alaska, Coast Guard warns residents

The first wave from a small tsunami has been reported in a southeast Alaska community.

State officials say a wave with a height of about 4 inches was measured in Craig late Saturday evening.

That was smaller than earlier forecasts, which said the wave could have been up to 1 foot.

Parts of southeast Alaska and the Canadian coast remain under a tsunami warning.

The warning was sparked by a strong earthquake Saturday night that shook off the west coast of Canada. The U.S. Geological Survey said the 7.7-magnitude earthquake hit in the Queen Charlotte Islands area, followed by a 5.8-magnitude aftershock several minutes later.
