On May 26, 2022 at 22:25 UTC, a magnitude 3.7 shallow crustal earthquake struck 105 km ESE of Akutan, Alaska, at a depth of 50.2 km and coordinates 53.9530°, -164.1961°.

Physical scale: An earthquake of magnitude 3.7 releases seismic energy equivalent to roughly 5.4 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 215 m — a useful intuition for the size of the slip patch on the fault.
