Scientists with NASA/Caltech's
Advanced Rapid Imaging and Analysis
project (ARIA) used new satellite data to produce a map of ground deformation on the resort island of Lombok, Indonesia, following a deadly 6.9-magnitude earthquake on August 5.
The false-color map shows the amount of permanent surface movement that occurred, almost entirely due to the quake, over a six-day period between satellite images taken on July 30 and August 5.
From the pattern of deformation in the map, scientists have determined that the earthquake fault slip was on a fault beneath the northwestern part of Lombok Island, and it caused as much as 10 inches (25 centimeters) of uplift of the ground surface. White areas in the image are places where the radar measurement was not possible, largely due to dense forests in the middle of the islands.
Through these maps, NASA and its partners are contributing important observations and expertise that can assist with response to earthquakes and other natural or human-produced hazards.
