On May 7, 2022 at 17:26 UTC, a magnitude 3.2 intermediate depth earthquake struck 12 km W of Sand Point, Alaska, at a depth of 70.8 km and coordinates 55.3197°, -160.6895°.

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.
