On July 10, 2024 at 22:12 UTC, a magnitude 3.5 shallow crustal earthquake struck 263 km S of False Pass, Alaska, at a depth of 10.0 km and coordinates 52.5241°, -162.6893°.

Physical scale: An earthquake of magnitude 3.5 releases seismic energy equivalent to roughly 2.7 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 157 m — a useful intuition for the size of the slip patch on the fault.
