On May 1, 2026 at 02:13 UTC, a magnitude 3.2 intermediate depth earthquake struck 10 km NNE of Brenas, Puerto Rico, at a depth of 97.5 km and coordinates 18.5485°, -66.2970°.
Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 1.0 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 100 m — a useful intuition for the size of the slip patch on the fault.
