On August 25, 2021 at 23:27 UTC, a magnitude 3.9 intermediate depth earthquake struck 11 km ESE of Guaymate, Dominican Republic, at a depth of 109.0 km and coordinates 18.5486°, -68.8825°.
Physical scale: An earthquake of magnitude 3.9 releases seismic energy equivalent to roughly 12 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 310 m — a useful intuition for the size of the slip patch on the fault.
