"earthquake"

Residents from Juneau, Haines, Whitehorse and other Southeast Alaska towns reported houses shaking briefly.

Alaska communities in the Aleutians were under a tsunami advisory Tuesday after a magnitude 8.8 earthquake struck off the coast of Kamchatka at about 3:25 p.m. Alaska time.

The Alaska Earthquake Center reported about 30 aftershocks in the two hours after the quake. The largest aftershock so far had a magnitude of 5.2.

Monday’s quake near Egegik was the area’s strongest in over a decade. Scientists say it was likely caused by normal fault movement, but are monitoring volcanic activity.

There were 39,836 seismic events in Alaska and nearby regions in 2024, according to the Alaska Earthquake Center’s newly released 2024 Alaska Seismicity Summary.

A magnitude 5.6 earthquake struck about 58 miles southwest of Unalaska Sunday afternoon. Many locals felt the event, including in Nikolski and Akutan.

Earthquakes in the Nenana Basin in Interior Alaska last longer and feel much stronger than quakes of comparable magnitude in other places. University of Alaska Fairbanks scientists are studying why.

The Alaska Earthquake Center said the quake was an aftershock of the magnitude 8.2 earthquake that reverberated in communities along the Alaska Peninsula in July — the country’s largest in half a century.

The magnitude 8.2 earthquake that struck off Alaska’s southwest coast Wednesday night gave nearby residents a good shake and triggered tsunami warnings, but there were no large waves or any immediate reports of major damage or injuries.

The quake has triggered a tsunami warning for a swath of coastal Alaska from Sand Point to Kodiak to Homer to Cordova, and prompted sirens to sound in communities as evacuations began.
