A minor magnitude 3.1 earthquake struck near Dominican Republic on Saturday, September 12, 2026 at 06:51:38 PM UTC. This shallow crustal event (43.3 km depth) released energy equivalent to approximately 674 kg of TNT. Here is the verified UASD telemetry, live epicenter map, and ground shaking assessment.

A magnitude 3.1 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 43.3 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.
Micro-tremors and minor events of this scale are part of ongoing background tectonic relaxation. While isolated micro-aftershocks may occur, the likelihood of a damaging secondary event remains statistically low under normal seismic conditions.
