On July 26, 2026 at 04:57 UTC, a magnitude 3.3 shallow crustal earthquake struck 96 km N of Suárez, Puerto Rico, at a depth of -0.1 km and coordinates 19.2878°, -65.6875°.
Physical scale: An earthquake of magnitude 3.3 releases seismic energy equivalent to roughly 1.4 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 118 m — a useful intuition for the size of the slip patch on the fault.
