On July 19, 2026 at 14:29 UTC, a magnitude 3.2 shallow crustal earthquake struck 72 km NNE of Vieques, Puerto Rico, at a depth of 45.2 km and coordinates 19.0070°, -65.5127°.
Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 951 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 97 m — a useful intuition for the size of the slip patch on the fault.
