M3.2 Earthquake 14 km NNE of Meadow Lakes, Alaska — September 1, 2025
2025-09-01 22:31:14 UTC (2025-09-01) · approx. 12:31 PM UTC-10 local
Felt by 40 people across nearby locations.
On September 1, 2025 at 22:31 UTC, a magnitude 3.2 shallow crustal earthquake struck 14 km NNE of Meadow Lakes, Alaska, at a depth of 54.7 km and coordinates 61.7512°, -149.5257°. The earthquake was reported felt by 40 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 2.7 (weak).
Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 951 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 97 m — a useful intuition for the size of the slip patch on the fault.
The epicenter is located in Alaska, a region characterized by Pacific Plate subduction beneath the North American Plate, producing frequent megathrust and crustal earthquakes along the Aleutian arc. The nearest mapped fault system is the Aleutian megathrust. View all earthquakes in Alaska.

Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 3.2 earthquakes can continue for several days and gradually diminish over time.
Has Alaska had earthquakes this big before?
The largest recorded earthquake in Alaska was the M9.2 Great Alaska earthquake of March 27, 1964. Today's magnitude 3.2 event is significantly smaller than that historical record.
