Port-au-prince earthquake
At 4:53 p.m. Eastern time on Jan. 12, 2010, an earthquake measuring 7.0 on the Richter scale struck 10 miles southwest of Haiti's capital, Port-au-Prince, causing catastrophic damage by collapsing office buildings, roads, schools, hospitals, hotels, and thousands of flimsy houses precariously built on steep mountainsides. It was the most powerful earthquake to hit the region in over 250 years.
