2023-11-23 19:58:20 UTC (2023-11-23) · approx. 3:58 PM UTC-4 local
On November 23, 2023 at 19:58 UTC, a magnitude 3.1 shallow crustal earthquake struck near Mona Passage, at a depth of 14.7 km and coordinates 18.0588°, -67.2403°.
Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 651 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 82 m — a useful intuition for the size of the slip patch on the fault.
