On July 14, 2026 at 07:51 UTC, a magnitude 3.8 shallow crustal earthquake struck 80 km W of Akhiok, Alaska, at a depth of 0.0 km and coordinates 56.9840°, -155.4900°.

Physical scale: An earthquake of magnitude 3.8 releases seismic energy equivalent to roughly 7.6 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 252 m — a useful intuition for the size of the slip patch on the fault.
