On February 5, 2025 at 19:50 UTC, a magnitude 3.6 shallow crustal earthquake struck 165 km N of Suárez, Puerto Rico, at a depth of 49.0 km and coordinates 19.9045°, -65.5688°.

Physical scale: An earthquake of magnitude 3.6 releases seismic energy equivalent to roughly 4.5 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 199 m — a useful intuition for the size of the slip patch on the fault.
