On March 30, 2026 at 20:49 UTC, a magnitude 2.0 shallow crustal earthquake struck 7 km S of Big Lake, Alaska, at a depth of 24.4 km and coordinates 61.4570°, -149.9730°.

Physical scale: An earthquake of magnitude 2.0 releases seismic energy equivalent to roughly 15.1 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 14 m — a useful intuition for the size of the slip patch on the fault.

Common Questions

How strong was the magnitude 2.0 earthquake near Big Lake, Alaska?

The magnitude 2.0 earthquake that struck 7 km S of Big Lake, Alaska on March 30, 2026 at 20:49 UTC had a depth of 24.4 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 2.0 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.
