2022-08-30 18:35:32 UTC (2022-08-30) · approx. 2:35 PM UTC-4 local
On August 30, 2022 at 18:35 UTC, a magnitude 3.3 shallow crustal earthquake struck 75 km N of Tierras Nuevas Poniente, Puerto Rico, at a depth of 16.8 km and coordinates 19.1463°, -66.4498°.
Physical scale: An earthquake of magnitude 3.3 releases seismic energy equivalent to roughly 1.2 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 109 m — a useful intuition for the size of the slip patch on the fault.
