On August 9, 2025 at 20:49 UTC, a magnitude 3.4 intermediate depth earthquake struck 28 km E of Punta Cana, Dominican Republic, at a depth of 90.2 km and coordinates 18.5967°, -68.1327°.
Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 2.1 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 140 m — a useful intuition for the size of the slip patch on the fault.
