On October 29, 2023 at 18:11 UTC, a magnitude 3.0 intermediate depth earthquake struck near Mona Passage, at a depth of 99.6 km and coordinates 18.1015°, -67.2327°.

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.
