On January 19, 2026 at 21:47 UTC, a magnitude 3.0 shallow crustal earthquake struck 18 km WNW of Fishhook, Alaska, at a depth of 23.0 km and coordinates 61.8020°, -149.5700°.

Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 477 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 71 m — a useful intuition for the size of the slip patch on the fault.

Common Questions

How strong was the magnitude 3.0 earthquake near Fishhook, Alaska?

The magnitude 3.0 earthquake that struck 18 km WNW of Fishhook, Alaska on January 19, 2026 at 21:47 UTC had a depth of 23.0 km. 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 3.0 earthquakes can continue for several days and gradually diminish over time.

What should I do after an earthquake?

If you were in the affected area: check yourself and others for injuries, inspect your home for damage, and be prepared for aftershocks. For detailed guidance, see our earthquake safety guide and emergency planning resources.
