A minor magnitude 3.6 earthquake struck 119 km NE of Punta Cana, Dominican Republic on Saturday, September 12, 2026 at 11:48:02 AM UTC. This shallow crustal event (69.0 km depth) released energy equivalent to approximately 4 tons of TNT. Here is the verified PR telemetry, live epicenter map, and ground shaking assessment.

A magnitude 3.6 event is classified as a minor earthquake. Often felt by people indoors, especially on upper floors. Hanging objects may swing slightly; structural damage is extremely rare.
Felt by almost no one except under extraordinarily favorable conditions.

Earthquake strength is measured on a logarithmic scale. Compare this event with the full seismic scale:
Because seismic scales are logarithmic, each whole integer increase represents:
Dominican Republic's seismicity is fundamentally governed by its tectonic setting: Northern boundary of Caribbean Plate colliding obliquely with North American Plate across Hispaniola. Major regional fault structures include Septentrional Fault Zone, Enriquillo-Plantain Garden Fault, Hispaniola Trench.
Originating at a depth of 69.0 km (Earth's Crust (0–70 km)), this rupture occurred occurred within the brittle upper crust. shallow earthquakes produce the highest peak ground acceleration and the sharpest surface shaking.
Seismologists note that minor aftershocks remain common in the 24 to 48 hours following tremors of magnitude 3.6. According to statistical seismic models, there is roughly a 5% probability of a subsequent event of equal or greater strength occurring in the same fault zone. Residents in Dominican Republic are advised to check living spaces for unsecured items.
