On August 15, 2021 at 21:38 UTC, a magnitude 3.6 intermediate depth earthquake struck 53 km SE of Punta Cana, Dominican Republic, at a depth of 103.0 km and coordinates 18.2806°, -68.0030°.
Physical scale: An earthquake of magnitude 3.6 releases seismic energy equivalent to roughly 4.3 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 196 m — a useful intuition for the size of the slip patch on the fault.
