[1] The EPGFZ is named for Lake Enriquillo in the Dominican Republic where the fault zone emerges, and extends across the southern portion of Hispaniola through the Caribbean to the region of the Plantain Garden River in Jamaica.
The EPGFZ shares approximately half of the relative motion between the North American and Caribbean tectonic plates with the Septentrional-Oriente fault zone which runs along the northern side of Hispaniola.
[7] A temporary Canadian seismic sensor network of three stations has been established in Haiti along the fault, as of February 19, 2010.
The stations are in secure locations, being expensive equipment, and are satellite linked to Natural Resources Canada in Ottawa.
One station is at the Canadian Embassy in Port-au-Prince (in the suburb of Pétion-Ville, in the district of Juvénat), and has a permanent guard of one.
