On July 14, 2026 at 18:55 UTC, a magnitude 3.3 shallow crustal earthquake struck 106 km SE of False Pass, Alaska, at a depth of 9.7 km and coordinates 54.0862°, -162.4440°.

Physical scale: An earthquake of magnitude 3.3 releases seismic energy equivalent to roughly 1.3 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 114 m — a useful intuition for the size of the slip patch on the fault.
