Wired discusses the results of NASA’s first UAVSAR 3D image of the devastated area:
NASA’s radar-equipped jet has returned its first 3-D image of Port-au-Prince, Haiti. This false-color image clearly shows the Enriquillo-Plantain Garden Fault extending east of the city.
The image supports a Jan. 21 U.S. Geological Survey report that suggested the section of the fault (indicated by the black arrow above) nearest to Port-au-Prince (yellow arrow) did not slip significantly in the magnitude 7 Jan. 12 earthquake.
The new image, taken by JPL’s Uninhabited Aerial Vehicle Synthetic Aperture Radar attached to a modified Gulfstream III jet, shows that the ground rupture moved westward from the epicenter. The section of the fault in the image did not rupture, a situation that increases the risk of another significant earthquake in the future.

The colors in the image, which shows a swath of about 12.5 miles, are the result of three different radar polarizations that make vegetation appear green, water appear blue and urban areas look reddish.
