On August 13, 2026 at 03:41 UTC, a magnitude 3.4 intermediate depth earthquake struck 35 km SSE of Punta Cana, Dominican Republic, at a depth of 110.2 km and coordinates 18.3075°, -68.2222°.

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 129 m — a useful intuition for the size of the slip patch on the fault.
