List of major earthquakes in Haiti
• 1751 Port-au-Prince earthquake (18 October): According to French historian Moreau de Saint-Méry, "only one masonry building had not collapsed" in Port-au-Prince, Haiti's capital city. • 1770 Port-au-Prince earthquake (3 June): The city was leveled in this magnitude 7.5 quake, which killed over 200 people. • 1783: A strong quake partially destroyed the church in Santiago. • 1842 Cap-Haitien earthquake (7 May): An earthquake destroyed the city of Cap-Haïtien and other towns in the north of Haiti and the Dominican Republic; this earthquake also destroyed the Sans-Souci Palace. 10,000 people were killed. It has been estimated that its magnitude was 8.1. • 1946 Dominican Republic earthquake (4 August): This 8.0-magnitude quake in Samaná also shook Haiti horrifically, producing a tsunami that killed 1,600 people. • 2010 Haiti earthquake (12 January):. The epicentre of this magnitude 7.0 Mw earthquake was near Léogâne, approximately 25 km (16 miles) west of Port-au-Prince. at a depth of 13 km (8.1 miles). The United States Geological Survey recorded a series of at least 33 aftershocks, 14 of which were between magnitudes 5.0 and 5.9. The International Red Cross estimated that about three million people were affected by the quake; the Haitian Government reports that over 316,000 people had been identified as dead, an estimated 300,000 injured, and an estimated 1,000,000 homeless. The death toll is expected to rise. What causes the earthquake in Haiti?
The Enriquillo–Plantain Garden fault zone (EPGFZ or EPGZ) is a system of coaxial left lateral-moving strike slip faults which runs along the southern side of the island of Hispaniola, where the Dominican Republic and Haiti are located.[
three sides by the much larger North and South American plates, both of which are moving approximately westwards with respect to the Caribbean plate at around 2-3 centimetres a year. On the eastern edge of the plate, the boundary runs perpendicular to the direction of relative plate motion, so there is compression and subduction However, as the boundary curves around to form the northern boundary of the Caribbean plate, where the Haitian earthquake occurred, it starts to run parallel to the direction of relative plate motion, making strike-slip faulting along E-W trending faults the most likely expression of deformation in this region.
Haiti earthquake occurred at a fault that runs right through Haiti and is situated along the boundary between the Caribbean and North American plates, which are rocky slabs that cover the planet and fit together like a giant jigsaw puzzle. These two plates constantly creep past one another, about 0.8 inches a year, with the Caribbean plate moving eastward with respect to the North American slab. The island of Hispaniola lies across the complex transform plate boundary between the North American Plate and the Caribbean Plate. The overall four cm per year displacement along this boundary is split nearly equally between two major dextral (right lateral) strike-slip zones either side of the Gonâve Microplate. To the south is the Enriquillo–Plantain Garden fault zone, which extends from Jamaica in the west to the south-east of Hispaniola to the east. In the north the fault zone is the Septentrional-Oriente fault zone passing along the southern margin of Cuba and along the northern part of Hispaniola. Both of these fault zones have been associated with several major historical earthquakes 1842 Cap-Haitien earthquake
