The earthquake that happened in Haiti last January 12, 2010 really was a disaster.
Here's a detailed information about the earthquake.
The 2010 Haiti earthquake was a catastrophic magnitude 7.0 Mw earthquake centred approximately 25 kilometres (16 mi) from Port-au-Prince, the capital of Haiti, which struck at 16:53:09 local time (21:53:09 UTC) on Tuesday, 12 January 2010. The earthquake occurred at a depth of 13 kilometres (8.1 mi). The United States Geological Survery recorded a series of aftershocks, fourteen of them between magnitudes 5.0 and 5.9. The International Red Cross estimates that there have been as many as three million people affected by the quake, and an estimated 450,000–500,000 deaths.
Most of Port-au-Prince's major landmarks were significantly damaged or destroyed in the earthquake, including the Presidential Palace (though the President survived), the National Assembly building, the Port-au-Prince Cathedral, and the main jail. All hospitals were destroyed or so badly damaged that they have been abandoned. The United Nations reported that headquarters of the United Nations stabilization Mission in Haiti (MINUSTAH), located in the capital, collapsed and that a large number of UN personnel were unaccounted for. The Mission's Chief, Hedi Annabi, was confirmed dead on 13 January by President Rene Preval.
