2023-11-10 22:10:50 UTC (2023-11-10) · approx. 6:10 PM UTC-4 local
On November 10, 2023 at 22:10 UTC, a magnitude 3.4 shallow crustal earthquake struck 6 km ENE of La Parguera, Puerto Rico, at a depth of 15.0 km and coordinates 18.0040°, -66.9941°.
Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 1.7 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 127 m — a useful intuition for the size of the slip patch on the fault.
