Satellite Photos of Haiti Before and After the Earthquake

1. Satellite Photos of Haiti Before and After the Earthquake

January 14

By far our most popular gallery this year, in fact our most popular story of any sort, was a collection of satellite images of Haiti taken before and after the earthquake that struck near Port-au-Prince on January 12. These photos were released the following day by Google and the satellite imaging company GeoEye.

Seeing the devastation from above gave us a new view of the severity of this disaster, a new appreciation for what the country was dealing with, and the daunting task that lay ahead for rescuers and relief workers.

See the full gallery.
