Faces of Port-au-Prince

This photo was taken by USGS seismologist Susan Hough two months after the magnitude-7 earthquake struck Port-au-Prince on Jan. 12, 2010. Dr. Hough traveled to Haiti with USGS colleagues Doug Given, Mark Meremonte, and J. Zebulon Maharrey to install seismometers, which monitor the earth's movement and can detect and measure aftershocks. The installation of seismometers helps USGS scientists understand why some parts of Port-au-Prince experienced more damage from the earthquake than others and which areas are most vulnerable for future earthquakes.
