Pedro Bay, Alaska – A magnitude 3.1 earthquake struck deep beneath southwest Alaska at 9:17 a.m. Friday, with the epicenter located about 58 miles east of Pedro Bay, prompting monitoring across the Lake and Peninsula region.
According to the Alaska Earthquake Center, the quake originated 123 kilometers below the surface, a depth that typically reduces surface shaking and limits damage risk. The event was automatically detected and reviewed, with no immediate reports of shaking impacts or infrastructure issues.
Communities near Iliamna Lake, including Pedro Bay and surrounding rural areas, may have experienced little to no noticeable movement due to the depth. No disruptions have been reported on regional air routes or along local access roads, and utilities remain stable.
Seismologists note that deep earthquakes like this are common in Alaska’s active subduction zone, where the Pacific Plate moves beneath the North American Plate. These events rarely produce significant surface effects but are closely tracked for patterns.
Residents are encouraged to remain aware of emergency alerts and review preparedness plans, especially in remote areas where response times can vary. Additional updates will follow if aftershocks or related activity develop through the day.
