On September 24, 2022 at 19:46 UTC, a magnitude 3.2 shallow crustal earthquake struck 58 km SE of Nikolski, Alaska, at a depth of 37.0 km and coordinates 52.5353°, -168.3040°.

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.
