2020-11-26 20:58:33 UTC (2020-11-26) · approx. 4:58 PM UTC-4 local
On November 26, 2020 at 20:58 UTC, a magnitude 3.2 shallow crustal earthquake struck 15 km S of Guánica, Puerto Rico, at a depth of 11.0 km and coordinates 17.8321°, -66.9073°.
Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 985 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 99 m — a useful intuition for the size of the slip patch on the fault.
