On May 6, 2022 at 23:19 UTC, a magnitude 3.2 shallow crustal earthquake struck near Alaska Peninsula, at a depth of 46.1 km and coordinates 56.3167°, -156.5242°.

Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 951 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 97 m — a useful intuition for the size of the slip patch on the fault.
