2026-09-13 14:06:10 UTC (1 hour ago) · approx. 10:06 AM UTC-4 local
On September 13, 2026 at 14:06 UTC, a magnitude 3.2 intermediate depth earthquake struck 122 km N of Culebra, Puerto Rico, at a depth of 80.0 km and coordinates 19.4113°, -65.2633°.
Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 1.0 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 100 m — a useful intuition for the size of the slip patch on the fault.
