On October 6, 2022 at 23:49 UTC, a magnitude 3.2 intermediate depth earthquake struck 5 km SSW of Stella, Puerto Rico, at a depth of 86.8 km and coordinates 18.2822°, -67.2712°.

Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 919 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 96 m — a useful intuition for the size of the slip patch on the fault.
