2022-11-19 23:41:05 UTC (2022-11-19) · approx. 7:41 PM UTC-4 local
On November 19, 2022 at 23:41 UTC, a magnitude 3.3 shallow crustal earthquake struck 41 km N of Culebra, Puerto Rico, at a depth of 57.2 km and coordinates 18.6793°, -65.2588°.
Physical scale: An earthquake of magnitude 3.3 releases seismic energy equivalent to roughly 1.1 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 105 m — a useful intuition for the size of the slip patch on the fault.
