NASA's ARIA Project Generates New Satellite-Derived Map of Ground Deformation from Latest Mexico Quake

Scientists with the Advanced Rapid Imaging and Analysis project (ARIA), a collaboration between NASA's Jet Propulsion Laboratory in Pasadena, California, and Caltech, also in Pasadena, using synthetic aperture radar (SAR) data from the European Union's Copernicus Sentinel-1B satellite, operated by the European Space Agency, generated a map of the deformation of Earth's surface caused by the Feb. 16, 2018 magnitude 7.2 Pinotepa earthquake in Oaxaca, Mexico. The deformation map is produced from automated interferometric processing of the SAR data using the JPL ARIA data system in response to a signal received from the U.S. Geological Survey. The false-color map shows the amount of permanent surface movement that occurred almost entirely due to the quake, as viewed by the satellite, during a 12-day interval between two Sentinel-1 images acquired on Feb. 5 and Feb. 17, 2018.
