On May 14, 2026 at 02:53 UTC, a magnitude 4.2 shallow crustal earthquake struck 92 km SE of False Pass, Alaska, at a depth of 50.3 km and coordinates 54.2286°, -162.4686°.

Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
