On January 25, 2022 at 21:42 UTC, a magnitude 3.4 intermediate depth earthquake struck 28 km NNE of Vieques, Puerto Rico, at a depth of 88.0 km and coordinates 18.6458°, -65.6880°.
Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 1.8 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 132 m — a useful intuition for the size of the slip patch on the fault.
