* The North American Plate: This plate is on the north side of the fault.
* The Caribbean Plate: This plate is on the south side of the fault.
The earthquake occurred along the Enriquillo-Plantain Garden Fault Zone, which is a transform fault that separates these two plates. This means that the plates slide horizontally past each other.
The specific location of the 2010 Haiti earthquake was where the North American Plate moved westward relative to the Caribbean Plate, causing a slippage along the fault. This slippage released a massive amount of energy, which resulted in the devastating earthquake.
