Hispaniola is an island in the Caribbean, home to the countries of Haiti and the Dominican Republic. The tectonic activity in this region is primarily influenced by the boundary between the North American and Caribbean tectonic plates. This interaction leads to significant geological features, including mountains and earthquakes. The island's tectonics are characterized by complex fault systems, such as the Enriquillo-Plantain Garden Fault, which can cause seismic events. The movement of these plates contributes to the island's diverse landscape and poses risks for its inhabitants due to potential natural disasters.
