On October 31, 2025 at 21:11 UTC, a magnitude 3.6 shallow crustal earthquake struck 52 km NNE of Miches, Dominican Republic, at a depth of 30.0 km and coordinates 19.3856°, -68.7891°.

Physical scale: An earthquake of magnitude 3.6 releases seismic energy equivalent to roughly 3.5 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 178 m — a useful intuition for the size of the slip patch on the fault.
