On July 14, 2026 at 17:30 UTC, a magnitude 3.2 shallow crustal earthquake struck 187 km SE of Chignik, Alaska, at a depth of 12.0 km and coordinates 55.0390°, -156.4230°.

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.
