Here's Looking @ Earth — Aqua's ASTER's Haitian Landslide Exam


The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument on NASA's Terra spacecraft captured this simulated natural color image of the Port-au-Prince, Haiti, area, January 14, 2010, two days after a magnitude 7.0 earthquake struck the region and caused massive damage and loss of life.

While ASTER's 15-meter (50-foot) resolution is not sufficient to see damaged buildings, it can be used to identify other results of the shaking. The red circles superimposed on the image indicate possible landslides, a common occurrence in mountainous terrain after large earthquakes. The possible landslides were identified by carefully comparing the new image with an image acquired one year previously.
