Flexi Says: The earthquake that devastated Port-au-Prince, Haiti in 2010 occurred along a transform boundary on the the Enriquillo-Plantain Garden fault system. The system of faults and plates in the Caribbean is complex, with areas of subduction and transform motion, and broken sections of crust that form microplates. The Caribbean plate is moving east in relation to the North American plate, and between them lies the Gonave microplate. The Enriquillo-Plantain Garden fault system separates the Caribbean plate and Gonave microplate.
