On April 27, 2024 at 22:13 UTC, a magnitude 3.0 shallow crustal earthquake struck 151 km S of False Pass, Alaska, at a depth of 18.0 km and coordinates 53.5034°, -163.7297°.

Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 477 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 71 m — a useful intuition for the size of the slip patch on the fault.
