A tsunami advisory was in effect in some coastal areas, NWS officials said.
A powerful 7.2-magnitude earthquake struck near the Alaska Peninsula late Saturday.
The quake prompted the National Weather Service to issue a tsunami warning early Sunday, saying there was a risk of “significant inundation,” an alert that was downgraded to an advisory shortly afterward.
“If you are located in this coastal area, move off the beach and out of harbors and marinas,” officials at the National Tsunami Warning Center said in the advisory.
Preliminary data placed the quake about 55 miles southwest of Sand Point, Alaska, with a magnitude of 7.2, the weather service said. The quake had initially been measured at a magnitude of 7.4, the United States Geological Survey said on Twitter.
It struck at about 10:48 p.m. local time.
The earlier tsunami warning had listed times spanning about 90 minutes when tsunami waves were expected to hit the shore “from Chignik Bay to Unimak Pass.”
“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.”
