The month's largest event in the Dominican Republic was a magnitude 5.2 earthquake near Ramón Santana, Dominican Republic on 27 September 2026 at 21:49 UTC. A magnitude 5.2 earthquake radiates roughly 951 tons of TNT equivalent in seismic energy.

45% of events here are shallow (under 70 km), 55% intermediate (70–300 km) and 0% deep-focus (over 300 km). A substantial share of intermediate-depth events points to a subducting slab beneath the region rather than purely crustal faulting.

By band, the catalogue holds 3 in the magnitude 2 range, 23 in the magnitude 3 range, 2 in the magnitude 4 range, 1 in the magnitude 5 range.
