On October 18, 2026 at 18:28 UTC, a magnitude 3.4 shallow crustal earthquake struck 67 km NNE of Punta Cana, Dominican Republic, at a depth of 21.0 km and coordinates 19.1703°, -68.2420°.
Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 1.8 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 132 m — a useful intuition for the size of the slip patch on the fault.
