2026-11-06 10:59:41 UTC (1 hour ago) · approx. 6:59 AM UTC-4 local
On November 6, 2026 at 10:59 UTC, a magnitude 3.1 shallow crustal earthquake struck 62 km NNE of Luquillo, Puerto Rico, at a depth of 60.2 km and coordinates 18.8922°, -65.4767°.
Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 801 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 90 m — a useful intuition for the size of the slip patch on the fault.
