On July 10, 2026 at 09:04 UTC, a magnitude 3.2 shallow crustal earthquake struck 5 km E of La Parguera, Puerto Rico, at a depth of 7.9 km and coordinates 17.9700°, -66.9950°.

Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 1.1 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 102 m — a useful intuition for the size of the slip patch on the fault.
