- 7.0 magnitude earthquake on the Richter scale and caused by the collision of the North American and Caribbean plates.
- Estimated casualties 300,000
Damage to infrastructure in the 2010 Haiti earthquake was extensive and affected areas included Port-au-Prince, Petit-Goâve, Léogâne, Jacmel and other settlements in southwestern Haiti. In February Prime Minister Jean-Max Bellerive estimated that hundreds of residences and commercial buildings had collapsed or were severely damaged. The deputy mayor of Léogâne, which was at the epicenter of the earthquake, reported that 78% percent of the buildings in that city had been destroyed and Léogâne had "to be greatly rebuilt."
Many notable landmark buildings were significantly damaged or destroyed, including the Presidential Palace, the National Assembly building, the Port-au-Prince Cathedral, and the main jail. The Ministry of Education estimated that half the nation's primary schools and secondary schools were severely damaged or destroyed. In addition, the three main universities in Port-au-Prince were also severely damaged.
Other affected infrastructure included telephone networks, radio station, factories, and museums. Poor infrastructure before the earthquake only made the aftermath worse. It would many days to make a trip of a few miles because of the severe rubble and dead bodies. The roads would also crisscross haphazardly due to disorganized construction.
