On July 13, 2024 at 19:52 UTC, a magnitude 3.2 shallow crustal earthquake struck 85 km SE of Akutan, Alaska, at a depth of 36.5 km and coordinates 53.5926°, -164.8486°.

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.
