On June 18, 2023 at 22:16 UTC, a magnitude 3.4 shallow crustal earthquake struck 89 km NNE of Punta Cana, Dominican Republic, at a depth of 26.7 km and coordinates 19.2733°, -67.9570°.
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 138 m — a useful intuition for the size of the slip patch on the fault.
