On March 31, 2025 at 17:49 UTC, a magnitude 3.0 intermediate depth earthquake struck 23 km N of Suárez, Puerto Rico, at a depth of 79.0 km and coordinates 18.6442°, -65.8415°.
Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 548 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 75 m — a useful intuition for the size of the slip patch on the fault.
