On March 12, 2025 at 20:48 UTC, a magnitude 3.2 shallow crustal earthquake struck 4 km SSE of Indios, Puerto Rico, at a depth of 14.0 km and coordinates 17.9585°, -66.8093°. The earthquake was reported felt by 2 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 3.1 (light).

Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 919 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 96 m — a useful intuition for the size of the slip patch on the fault.
