2025-07-11 16:24:10 UTC (2025-07-11) · approx. 12:24 PM UTC-4 local
On July 11, 2025 at 16:24 UTC, a magnitude 2.6 shallow crustal earthquake struck 31 km N of Brenas, Puerto Rico, at a depth of 52.7 km and coordinates 18.7537°, -66.3203°.
Physical scale: An earthquake of magnitude 2.6 releases seismic energy equivalent to roughly 142 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 41 m — a useful intuition for the size of the slip patch on the fault.
