2025-07-13 18:31:33 UTC (2025-07-13) · approx. 2:31 PM UTC-4 local
On July 13, 2025 at 18:31 UTC, a magnitude 3.0 shallow crustal earthquake struck 73 km N of Tierras Nuevas Poniente, Puerto Rico, at a depth of 18.3 km and coordinates 19.1220°, -66.5067°.
Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 494 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 72 m — a useful intuition for the size of the slip patch on the fault.
