2023-05-19 21:37:46 UTC (2023-05-19) · approx. 4:37 PM UTC-5 local
On May 19, 2023 at 21:37 UTC, a magnitude 3.4 intermediate depth earthquake struck near Mona Passage, at a depth of 95.5 km and coordinates 19.1590°, -67.6578°.
Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 1.8 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 132 m — a useful intuition for the size of the slip patch on the fault.
