Jamaica is associated with the Gonave micro-plate, which is demarcated by the Oriente Fracture Zone (OFZ) to the north, the Walton (WFZ) and Enriquillo Fault Zones (EFZ) to the south and the Cayman Spreading Centre (CSC) to the west. The OFZ, spanning a distance of over 1000 kilometres, from south of Grand Cayman to the north coast of Haiti, is known to be a left-lateral strike-slip fault which means there is a relative westerly drift of Cuba (on the North American Plate) with respect to Jamaica.

The Walton and Enriquillo Faults are also left-lateral strike-slip features that separate the Gonave sliver from the Caribbean Plate to the south. Measurements made using Global Positioning System (GPS) indicate 18 mm/year of lateral strain and 3mm/yr of convergence on the OFZ near south-eastern Cuba, and 8-11 mm/yr on Jamaica.
