On March 17, 2024 at 20:03 UTC, a magnitude 3.2 intermediate depth earthquake struck near Rat Islands, Aleutian Islands, Alaska, at a depth of 138.5 km and coordinates 51.8619°, 178.2155°.

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.
