M4.4 Earthquake 68 km ENE of Kodiak, Alaska — April 24, 2025
2025-04-24 15:14:18 UTC (2025-04-24) · approx. 5:14 AM UTC-10 local
Felt by 89 people across nearby locations.
On April 24, 2025 at 15:14 UTC, a magnitude 4.4 shallow crustal earthquake struck 68 km ENE of Kodiak, Alaska, at a depth of 21.4 km and coordinates 58.0201°, -151.3264°. The earthquake was reported felt by 89 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 3.4 (light).
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 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 4.4 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 4.4 event is significantly smaller than that historical record.
