Évents thermaux d'Azua in the Azua Province of the Dominican Republic are chloride-rich geothermal vents located in the arid southern region of Hispaniola, where the complex Caribbean tectonic plate interaction has produced scattered geothermal activity in an otherwise dry and sparsely populated landscape. The Azua basin sits within one of the Caribbean's most seismically active zones, reflecting the collision between the North American and Caribbean plates that shapes Hispaniola's geology and occasional devastating earthquakes. The thermal vents provide a visible expression of the tectonic forces underlying this region, attracting geological curiosity as well as local communities seeking natural warm water resources in an area with limited water infrastructure.

Insider tip — The thermal vents near Azua emerge in the arid south of the Dominican Republic, where Caribbean tectonic activity drives geothermal energy to the surface. The surrounding dry scrubland contrasts dramatically with the lush north of the island, creating a stark landscape around the springs. Local communities use the warm waters for bathing and laundry, preserving an authentic vernacular hot spring culture. The nearby Enriquillo Basin, the lowest point in the Caribbean, adds geological drama to the visit.
