On March 27, 2026 at 22:24 UTC, a magnitude 3.0 shallow crustal earthquake struck 15 km NNE of Carrizales, Puerto Rico, at a depth of 13.2 km and coordinates 18.6187°, -66.7432°.0

Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 477 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 71 m — a useful intuition for the size of the slip patch on the fault.
