On October 10, 2026 at 16:32 UTC, a magnitude 3.4 intermediate depth earthquake struck 31 km NE of Punta Cana, Dominican Republic, at a depth of 83.5 km and coordinates 18.7587°, -68.1685°.

Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 1.6 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 123 m — a useful intuition for the size of the slip patch on the fault.
