2023-02-13 22:08:58 UTC (2023-02-13) · approx. 6:08 PM UTC-4 local
On February 13, 2023 at 22:08 UTC, a magnitude 3.3 shallow crustal earthquake struck 52 km N of Suárez, Puerto Rico, at a depth of 13.9 km and coordinates 18.9030°, -65.8322°.
Physical scale: An earthquake of magnitude 3.3 releases seismic energy equivalent to roughly 1.3 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 110 m — a useful intuition for the size of the slip patch on the fault.
