On June 16, 2020 at 17:42 UTC, a magnitude 3.8 intermediate depth earthquake struck 20 km E of Boca de Yuma, Dominican Republic, at a depth of 147.0 km and coordinates 18.3456°, -68.4135°.

Physical scale: An earthquake of magnitude 3.8 releases seismic energy equivalent to roughly 7.3 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 248 m — a useful intuition for the size of the slip patch on the fault.
