The quake, with a magnitude estimated at 7.0, caused the collapse of the National Palace, leveled countless shantytown dwellings and brought more suffering to a nation that was already the hemisphere’s poorest and most disaster-prone.
The earthquake was the worst in the region in more than 200 years and left the country in a shambles. As night fell in Port-au-Prince, Haiti’s densely populated capital, fires burned near the shoreline downtown, but otherwise the city fell into darkness.
