2026-11-10 08:48:04 UTC (1 hour ago) · approx. 4:48 AM UTC-4 local
On November 10, 2026 at 08:48 UTC, a magnitude 3.7 shallow crustal earthquake struck 69 km N of Culebra, Puerto Rico, at a depth of 14.0 km and coordinates 18.9285°, -65.2388°.
Physical scale: An earthquake of magnitude 3.7 releases seismic energy equivalent to roughly 5.0 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 209 m — a useful intuition for the size of the slip patch on the fault.
