On December 1, 2024 at 22:26 UTC, a magnitude 4.4 shallow crustal earthquake struck 164 km S of False Pass, Alaska, at a depth of 9.8 km and coordinates 53.3723°, -163.4453°.

Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
