On May 13, 2026 at 22:07 UTC, a magnitude 3.5 shallow crustal earthquake struck 32 km WNW of Ivanof Bay, Alaska, at a depth of 5.0 km and coordinates 56.0360°, -159.9390°.

Physical scale: An earthquake of magnitude 3.5 releases seismic energy equivalent to roughly 2.7 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 157 m — a useful intuition for the size of the slip patch on the fault.

Common Questions

How strong was the magnitude 3.5 earthquake near Ivanof Bay, Alaska?

The magnitude 3.5 earthquake that struck 32 km WNW of Ivanof Bay, Alaska on May 13, 2026 at 22:07 UTC had a depth of 5.0 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 3.5 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.
