On October 16, 2021 at 23:14 UTC, a magnitude 3.6 shallow crustal earthquake struck 91 km NE of Punta Cana, Dominican Republic, at a depth of 56.0 km and coordinates 19.1243°, -67.7496°.
Physical scale: An earthquake of magnitude 3.6 releases seismic energy equivalent to roughly 4.1 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 190 m — a useful intuition for the size of the slip patch on the fault.
