JUNEAU, Alaska (AP) — A reported 7.5 magnitude earthquake off the Alaska Peninsula on Monday prompted tsunami warnings for a vast swath of communities, leading some schools in the Kenai Peninsula Borough School District to evacuate and send students to higher ground.
The warning was issued by the National Tsunami Warning Center, following an earthquake off Sand Point. The Alaska Earthquake Center said the quake was widely felt in communities along the southern coast, including Sand Point, Chignik, Unalaska and the Kenai Peninsula.
The Alaska Earthquake Center said a magnitude 5.2 aftershock was reported 11 minutes later, centered roughly in the same area. Public safety officials in King Cove sent out an alert urging residents in the coastal area to move inland to higher ground.
Tsunami risk along the West Coast was still being evaluated by the National Weather Service as of 3 p.m. on Monday afternoon. Within an hour, however, the agency determined that there was no threat of tsunami beyond coastal Alaska.
"After a further evaluation, there is no threat for a tsunami on the US West Coast," NWS said. "Again, no threat to the Oregon coast for a Tsunami."
We are in communication with the National Tsunami Warning Center who is evaluating the threat. We have a couple of hours before anything would happen here. Please continue to stay tuned. We'll pass along any info as needed. Otherwise, info at https://t.co/2UGQtZtN8y https://t.co/6JoLTwzrYV
