A 7.5-magnitude earthquake on 28 September in northern Indonesia and the devastating tsunami that followed it killed more than 1,400 people and left a large trail of destruction.

This map, produced by NASA's Advanced Rapid Imaging and Analysis (ARIA) team, shows that damage. The map covers an area of about 42 by 44 miles (67 by 70 kilometers), shown by the red polygon. Each pixel measures about 33 yards (30 meters) across. The color variation from yellow to red represents increasingly more significant ground surface change, or damage likely caused by the earthquake and tsunami.
