On December 23, 2024 at 17:07 UTC, a magnitude 3.2 shallow crustal earthquake struck 8 km WSW of Guánica, Puerto Rico, at a depth of 15.4 km and coordinates 17.9358°, -66.9743°.

Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 829 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 91 m — a useful intuition for the size of the slip patch on the fault.
