On May 28, 2026 at 08:45 UTC, a magnitude 3.2 shallow crustal earthquake struck 43 km SW of Nanwalek, Alaska, at a depth of 57.2 km and coordinates 59.0780°, -152.4480°.

Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 951 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 97 m — a useful intuition for the size of the slip patch on the fault.
