On July 14, 2026 at 07:55 UTC, a magnitude 3.2 shallow crustal earthquake struck 1 km S of Guánica, Puerto Rico, at a depth of 13.6 km and coordinates 17.9620°, -66.9077°.

Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 858 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 93 m — a useful intuition for the size of the slip patch on the fault.
