On May 6, 2025 at 23:28 UTC, a magnitude 3.8 shallow crustal earthquake struck 28 km SW of Hope, Alaska, at a depth of 38.8 km and coordinates 60.7547°, -150.0428°. The earthquake was reported felt by 44 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 3.0 (light).

Physical scale: An earthquake of magnitude 3.8 releases seismic energy equivalent to roughly 7.6 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 252 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.

Common Questions

How strong was the magnitude 3.8 earthquake near Hope, Alaska?

The magnitude 3.8 earthquake that struck 28 km SW of Hope, Alaska on May 6, 2025 at 23:28 UTC had a depth of 38.8 km. It was felt by 44 people with maximum shaking intensity of MMI 3.0 (light). For context, this was a minor earthquake typically detected only by instruments.

Where did the earthquake occur?

The earthquake epicenter was located at 60.7547°, -150.0428°, which is 28 km SW of Hope, Alaska. View all earthquakes in Alaska.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 3.8 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 3.8 event is significantly smaller than that historical record.
