As many people along Hawaii's coasts rushed to higher ground, officials downgraded a tsunami warning to an advisory for southern Alaska and British Columbia. They also issued an advisory for areas of northern California and southern Oregon.
In Alaska, the wave or surge was recorded at 4 inches, much smaller than forecast, said Jeremy Zidek, a spokesman for the Alaska Department of Homeland Security and Emergency Management.
The U.S. Geological Survey said the earthquake hit in the Queen Charlotte Islands area. The quake was felt in Craig and other southeast Alaska communities, but Zidek said there were no immediate reports of damage.
Later Saturday evening, the warning for those areas was downgraded to an advisory, while a warning was issued for Hawaii. Early Sunday, the advisory was canceled entirely for Alaska.
In addition, officials issued an advisory for areas from Gualala Point, Calif., about 80 miles northwest of San Francisco, to the Douglas-Lane county line in Oregon, about 10 miles southwest of Florence.
