On 12 January 2010, a magnitude 7.0 earthquake struck in the arrondissement, the largest in Haiti in two centuries. The city of Port-au-Prince suffered much damage, and estimates of upwards of 50,000 deaths, with many facilities destroyed. In Pétionville, the earthquake collapsed a hospital in the city.
