A magnitude-6 earthquake struck at 8:11 a.m. AKST on Nov. 27, 2025, centered 37 miles northwest of Anchorage at a depth of 43 miles. Shaking was felt across Anchorage, the Matanuska-Susitna Borough, the Kenai Peninsula, and as far as Fairbanks.
Residents along the Lynn Canal experienced a jolting event on Monday afternoon that was later confirmed to be a magnitude 3 earthquake, which initially went undetected by seismic systems due to its location on the edge of the network.
Alaska researchers are developing a method to detect landslide-triggered tsunamis, aiming to provide early warnings for such unpredictable events.
Seismologists called the quake the most significant in the state’s largest city since 1964, in terms of how strong the ground itself shook.
Southeast Alaska had a very dry September. Heavy rains returned to the region this month, triggering a large mudslide on the Haines Highway.
