On June 30, 2026 at 21:27 UTC, a magnitude 3.4 shallow crustal earthquake struck 53 km S of Boca de Yuma, Dominican Republic, at a depth of 58.8 km and coordinates 17.8997°, -68.5475°.
Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 1.7 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 125 m — a useful intuition for the size of the slip patch on the fault.
