2025-02-14 19:17:48 UTC (2025-02-14) · approx. 3:17 PM UTC-4 local
On February 14, 2025 at 19:17 UTC, a magnitude 3.5 shallow crustal earthquake struck 82 km N of Tierras Nuevas Poniente, Puerto Rico, at a depth of 7.0 km and coordinates 19.2045°, -66.4561°.
Physical scale: An earthquake of magnitude 3.5 releases seismic energy equivalent to roughly 2.8 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 159 m — a useful intuition for the size of the slip patch on the fault.
