2022-03-27 17:57:22 UTC (2022-03-27) · approx. 1:57 PM UTC-4 local
On March 27, 2022 at 17:57 UTC, a magnitude 3.3 shallow crustal earthquake struck 64 km N of Tierras Nuevas Poniente, Puerto Rico, at a depth of 40.6 km and coordinates 19.0428°, -66.4603°.
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.
