The month's largest event in the Dominican Republic was a magnitude 4.3 earthquake near Ramón Santana, Dominican Republic on 21 March 2026 at 08:58 UTC. A magnitude 4.3 earthquake radiates roughly 43 tons of TNT equivalent in seismic energy.

That is close to the the Dominican Republic monthly average of 26 events over the period we cover, and down from the 29 recorded the previous month.

38% of events here are shallow (under 70 km), 62% 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 1 in the magnitude 2 range, 17 in the magnitude 3 range, 3 in the magnitude 4 range.

Activity peaked on 11 March, when 3 events were recorded.
