On May 2, 2026 at 14:13 UTC, a magnitude 3.1 shallow crustal earthquake struck 2 km ESE of Boquerón, Puerto Rico, at a depth of 12.9 km and coordinates 18.0160°, -67.1450°.

Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 629 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 80 m — a useful intuition for the size of the slip patch on the fault.
