On December 9, 2021 at 22:32 UTC, a magnitude 3.4 intermediate depth earthquake struck 15 km SW of San Rafael del Yuma, Dominican Republic, at a depth of 94.0 km and coordinates 18.3333°, -68.7781°.
Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 2.0 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 136 m — a useful intuition for the size of the slip patch on the fault.
