On June 22, 2023 at 19:24 UTC, a magnitude 3.4 shallow crustal earthquake struck 56 km W of Pole Ojea, Puerto Rico, at a depth of 22.1 km and coordinates 17.9323°, -67.7205°.
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.
