On September 9, 2022 at 19:24 UTC, a magnitude 4.2 shallow crustal earthquake struck 3 km E of Río San Juan, Dominican Republic, at a depth of 18.0 km and coordinates 19.6416°, -70.0424°.

Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
