On July 1, 2023 at 23:09 UTC, a magnitude 3.8 intermediate depth earthquake struck 18 km SE of Boca de Yuma, Dominican Republic, at a depth of 99.0 km and coordinates 18.2836°, -68.4675°.

Physical scale: An earthquake of magnitude 3.8 releases seismic energy equivalent to roughly 6.6 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 237 m — a useful intuition for the size of the slip patch on the fault.
