(Fox 10) – NASA unveiled a striking rainbow map showing how much the Earth moved after Southern California’s recent major earthquakes. A magnitude 6.4 earthquake on July 4 struck near the town of Ridgecrest, California, located about 150 miles northeast of Los Angeles. Later deemed a “foreshock,” the quake was followed by a larger magnitude 7.1 quake on July 5 in the same area, according to the U.S. Geological Survey.
NASA’s map, created by the Advanced Rapid Imaging and Analysis team at NASA’s Jet Propulsion Laboratory and California Institute of Technology, shows the surface displacement caused by both temblors. It was created by radar images taken before the earthquakes on April 16, 2018 and after on July 8, and scientists compared changes between the two. The team used images from the Japanese satellite ALOS-2. Each rainbow cycle represents 4.8 inches of ground displacement either toward or away from the satellite, NASA said. READ MORE
