On October 14, 2022 at 20:06 UTC, a magnitude 3.2 shallow crustal earthquake struck 158 km ESE of Akutan, Alaska, at a depth of 25.7 km and coordinates 53.4017°, -163.7112°.

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.
