On February 13, 2023 at 19:08 UTC, a magnitude 3.0 shallow crustal earthquake struck near Mona Passage, at a depth of 6.2 km and coordinates 18.1692°, -67.3615°.

Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 567 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 77 m — a useful intuition for the size of the slip patch on the fault.
