2026-05-30 22:07:42 UTC (2026-05-30) · approx. 6:07 PM UTC-4 local
On May 30, 2026 at 22:07 UTC, a magnitude 3.0 shallow crustal earthquake struck 3 km SSE of Boquerón, Puerto Rico, at a depth of 13.1 km and coordinates 18.0042°, -67.1535°.
Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 567 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 77 m — a useful intuition for the size of the slip patch on the fault.
