Moderate Earthquake Felt in Southcentral Alaska

TALKEETNA, Alaska (Nov. 9, 2025) — A moderate earthquake occurred in Southcentral Alaska late Friday, causing residents in Talkeetna, Anchorage, Chugiak, and surrounding areas to feel significant shaking.

The earthquake registered at a depth of 24.8 miles (40 km), with coordinates of 62.1712° N, 149.6946° W. The United States Geological Survey reported that the tremor was felt across a wide area, but no immediate damage or injuries have been reported.

According to a seismologist, earthquakes in this region are often generated by the interaction between the Pacific and North American tectonic plates. The largest earthquake in Alaska’s history, the 1964 M9.2 Great Alaska Earthquake, originated near Prince William Sound, highlighting the area’s seismic activity.

Recent notable earthquakes include the M7.1 Iniskin quake in 2016 and the M7.1 Anchorage quake in 2018, both resulting in significant ground shaking and damage to structures.

The current seismic event is classified under crustal seismicity, linked to faults and geological structures in the Cook Inlet basin and nearby areas. For example, the Castle Mountain Fault, located 25 miles (40 km) north of Anchorage, shows signs of previous earthquakes, including the M5.6 Sutton Earthquake in 1984.

As the region continues to experience seismic activity, monitoring agencies remain vigilant, ensuring public safety and preparedness.
