2023-07-07 22:40:27 UTC (2023-07-07) · approx. 5:40 PM UTC-5 local
On July 7, 2023 at 22:40 UTC, a magnitude 3.6 intermediate depth earthquake struck near Mona Passage, at a depth of 143.0 km and coordinates 18.1863°, -68.7285°.
Physical scale: An earthquake of magnitude 3.6 releases seismic energy equivalent to roughly 4.5 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 199 m — a useful intuition for the size of the slip patch on the fault.
