On November 15, 2026 at 05:15 UTC, a magnitude 3.9 shallow crustal earthquake struck 11 km E of Chenega, Alaska, at a depth of 14.7 km and coordinates 60.0860°, -147.8110°. The earthquake was reported felt by 6 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 3.7 (light).

Physical scale: An earthquake of magnitude 3.9 releases seismic energy equivalent to roughly 11 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 296 m — a useful intuition for the size of the slip patch on the fault.

Common Questions

How strong was the magnitude 3.9 earthquake near Chenega, Alaska?

The magnitude 3.9 earthquake that struck 11 km E of Chenega, Alaska on November 15, 2026 at 05:15 UTC had a depth of 14.7 km. It was felt by 6 people with maximum shaking intensity of MMI 3.7 (light). For context, this was a minor earthquake typically detected only by instruments.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 3.9 earthquakes can continue for several days and gradually diminish over time.

Understanding This Data

Magnitude 3.9 earthquakes are typically only recorded by instruments.
