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.

Tonga Cyclone Damage Mapped by NASA's ARIA Team

The Advanced Rapid Imaging and Analysis (ARIA) team at NASA's Jet Propulsion Laboratory created this Damage Proxy Map (DPM) of Tongatapu, the main island of Tonga, following the landfall of Cyclone Gita, a Category 4 storm that hit Tonga on Feb. 12-13, 2018. The map depicts areas that are likely damaged from the storm, shown by red and yellow pixels. The map was produced by comparing two pairs of interferometric synthetic aperture radar (InSAR) images from the COSMO-SkyMed satellites, operated by the Italian Space Agency (ASI). The pre- and post-cyclone images were acquired on Jan. 19 and Feb. 13, 2018, respectively. The later image was acquired just 4-1/2 hours after the peak damage by the cyclone.
