On May 4, 2024 at 20:11 UTC, a magnitude 3.8 intermediate depth earthquake struck 49 km W of Rincón, Puerto Rico, at a depth of 140.0 km and coordinates 18.3180°, -67.7145°.
Physical scale: An earthquake of magnitude 3.8 releases seismic energy equivalent to roughly 7.6 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 252 m — a useful intuition for the size of the slip patch on the fault.
