At least 1,297 people have died and another 5,700 are reported injured after a magnitude-7.2 earthquake struck Haiti on Saturday (Aug. 14), rocking the capital city and toppling buildings, according to the U.S. Geological Survey and news reports.
With the potential to hamper recovery efforts, the tropical depression Grace was also nearing the southern coast of Hispaniola, the island where Haiti is located, bringing high winds and the possibility of heavy rainfall to the area, CNN reported (opens in new tab).
The massive temblor's epicenter was about 5 miles (8 kilometers) from a city called Petit Trou de Nippes, and about 77 miles (125 km) west of the capital, Port-au-Prince. Shaking could be felt as far as Jamaica, roughly 2,000 miles (3,200 km) away, The New York Times reported.
Haiti's Prime Minister said on Sunday (Aug. 15) that he was sending aid to the hardest-hit areas, where hospitals are being overwhelmed with the onslaught of patients.
One hospital in Jeremie, in the southwestern part of Haiti, had to set up tents in its courtyard to accommodate the injured, CNN reported (opens in new tab). "There are a lot of people coming in — a lot of people," an administrator at the Hôpital Saint-Antoine in told CNN. "We don't have enough supplies."
The southwestern town of Les Cayes was almost completely demolished by the earthquake, according to Haiti's Prime Minister Ariel Henry. "The most important thing is to recover as many survivors as possible under the rubble," Henry said, as reported by The Associated Press. "We have learned that the local hospitals, in particular that of Les Cayes, are overwhelmed with wounded, fractured people."

In 2010, a magnitude-7.0 quake struck the capital, killing approximately 200,000 people and destroying much of Port-au-Prince. It has taken years for the country to rebuild after that quake.
Haiti sits near the boundary between two tectonic plates: the North American and Caribbean plates. The North American plate is creeping westward at the boundary at about 0.8 inches (20 millimeters) per year, according to USGS. Much of this slip is accommodated by a network of faults that snakes through the island of Hispaniola, where Haiti is located. The current quake, as well as the devastating 2010 quake, both struck along one of the southern faults in this network, known as the Enriquillo-Plantain Garden Fault. The most recent quake, however, was likely caused by lateral-slip, where one side of the fault slides past the other side, whereas the 2010 temblor was caused by thrust on a different portion of the fault, where one portion of the fault moves vertically relative to the other, according to USGS.
