On February 22, 2023 at 15:18 UTC, a magnitude 3.8 intermediate depth earthquake struck near Mona Passage, at a depth of 96.0 km and coordinates 18.2310°, -68.2605°.

Physical scale: An earthquake of magnitude 3.8 releases seismic energy equivalent to roughly 6.6 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 237 m — a useful intuition for the size of the slip patch on the fault.
