A 2007 earthquake hazard study by C. DeMets and M. Wiggins-Grandison noted that the Enriquillo-Plantain Garden fault zone could be at the end of its seismic cycle and concluded that a worst-case forecast would involve a 7.2 Mw earthquake, similar in size to the 1692 Jamaica earthquake [REF].
On 20 January at 06:03 local time (11:03 UTC) the strongest aftershock since the earthquake,[REF] measuring magnitude 5.9 Mw, struck Haiti [REF].
