NEW YORK — A powerful 7.2-magnitude earthquake struck near the Alaska Peninsula late Saturday.
Preliminary data placed the quake about 55 miles southwest of Sand Point, Alaska, the National Weather Service said. It had initially been measured at a magnitude of 7.4, the United States Geological Survey said on Twitter.
The quake prompted the National Weather Service in Anchorage to issue a brief tsunami warning, saying there was a risk of"significant inundation," an alert that was downgraded to an advisory before being canceled altogether early Sunday. The center's earlier update had been an advisory, urging locals near the coast to"move off the beach and out of harbors and marinas."
"Significant inundation is possible or already occurring," the service's Anchorage office said on Twitter in announcing the earlier warning."Move inland to higher ground."The earthquake was along the Alaska-Aleutian subduction zone, where large tremors are common, USGS officials said in a summary of the event.
