On February 21, 2022 at 23:00 UTC, a magnitude 2.3 shallow crustal earthquake struck 11 km SSE of Guánica, Puerto Rico, at a depth of 13.9 km and coordinates 17.8683°, -66.8810°.

Physical scale: An earthquake of magnitude 2.3 releases seismic energy equivalent to roughly 35.8 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 22 m — a useful intuition for the size of the slip patch on the fault.
