This bar indicates that you are within the PDS enterprise which includes 6 science discipline nodes and 2 support nodes which are overseen by the Project Management Office at NASA's Goddard Space Flight Center (GSFC). Each node is led by an expert in the subject discipline, supported by an advisory group of other practitioners of that discipline, and subject to selection and approval under a regular NASA Research Announcement.

Original Caption Released with Image:

The Advanced Rapid Imaging and Analysis (ARIA) team at NASA's Jet Propulsion Laboratory and California Institute of Technology — both in Pasadena, California — created this co-seismic Interferometric Synthetic Aperture Radar (InSAR) map that shows surface displacement caused by the recent major earthquakes in Southern California, including the magnitude 6.4 and the magnitude 7.1 events on July 4 and July 5, 2019, respectively.

The interferogram is derived from synthetic aperture radar (SAR) images from the ALOS-2 satellite, operated by the Japan Aerospace Exploration Agency (JAXA). The images were taken before (April 16, 2018) and after (July 8, 2019) the sequence of earthquakes. Each color cycle represents 4.8 inches (12 centimeters) of ground displacement in the radar line-of-sight.

The image covers an area of 31 by 78 miles (50 by 125 kilometers), and each pixel measures about 98 yards (90 meters) across. No filter was applied during the processing. The linear features across which the color fringes break indicate likely locations of surface rupture caused by the earthquakes, and the "noisy" areas may indicate locations where ground surface was disturbed by the earthquakes.

The ALOS-2 data were provided by JAXA. This task is funded by the NASA Disasters Program.
