2023-12-05 23:53:33 UTC (2023-12-05) · approx. 7:53 PM UTC-4 local
On December 5, 2023 at 23:53 UTC, a magnitude 3.2 intermediate depth earthquake struck 2 km SSW of Stella, Puerto Rico, at a depth of 108.3 km and coordinates 18.3050°, -67.2538°.
Physical scale: An earthquake of magnitude 3.2 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 102 m — a useful intuition for the size of the slip patch on the fault.
