The earthquake occurred 78 miles (125 km) west of the capital city of Port-au-Prince at a depth of 6.2 miles (10 kilometers).
The preliminary USGS PAGER report shows RED for shaking-related fatalities and economic losses – indicating high casualties are probable and significant damage is likely. Given the likely impact of this event, a significant international response seems likely.

The earthquake occurred in Haiti’s southwest peninsula, about 60 miles (100 km) west of the devastating January 2010 M 7.0 earthquake. Perceived shaking for today’s earthquake was very strong to severe at the epicenter and weak to light in Port-au-Prince. USGS scientists expect that this event will trigger aftershocks, but these will decrease in frequency over time.
Like the 2010 event, the faulting mechanism for this earthquake indicates oblique thrust faulting along the Enriquillo-Plantain Garden fault zone, the major fault structure and microplate boundary in the region.
