2025-06-24 23:08:33 UTC (2025-06-24) · approx. 7:08 PM UTC-4 local
On June 24, 2025 at 23:08 UTC, a magnitude 3.0 shallow crustal earthquake struck 26 km N of Garrochales, Puerto Rico, at a depth of 8.5 km and coordinates 18.6872°, -66.6077°.
Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 529 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 74 m — a useful intuition for the size of the slip patch on the fault.
