2025-03-27 20:05:27 UTC (2025-03-27) · approx. 4:05 PM UTC-4 local
On March 27, 2025 at 20:05 UTC, a magnitude 3.2 shallow crustal earthquake struck 74 km N of Tierras Nuevas Poniente, Puerto Rico, at a depth of 28.6 km and coordinates 19.1358°, -66.4430°.
Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 1.1 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 104 m — a useful intuition for the size of the slip patch on the fault.
