description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN STYLE="font-weight:bold;">Summary:</SPAN></P><P><SPAN>The Advanced Rapid Imaging and Analysis (ARIA) data system at NASA's Jet Propulsion Laboratory in Pasadena, California, automatically processed this interferogram or difference between two radar images. The maps were derived from synthetic aperture radar (SAR) data acquired on July 4 and July 10, 2019 (at 01:50 Universal Time) by the Copernicus Sentinel-1 satellites operated by the European Space Agency (ESA). The map covers an area of 90 by 170 kilometers. The processing averaged the pixels to about 30 meters across but not all of the resolution is maintained by the conversion to KMZ file. </SPAN></P><P><SPAN>The ground deformation measured by the satellite in this map is shown by color contours. Each color contour (blue to blue) indicates 2.8 cm (1.2 inches) of permanent ground motion in the direction towards the satellite (up and west). The wide zone of confused contours in the northwestern part of the rupture indicates complete ground motion, probably block rotation within the fault zone. Discontinuities in the color contours are nearly all due to faults, but there are some small magnitude but long discontinuities between the Sentinel-1 radar bursts because of the large north-south motion of the ground surface. Disregard any discontinuities that are exactly parallel to the top and bottom edges of the image.</SPAN></P><P><SPAN STYLE="font-weight:bold;">Suggested Use:</SPAN></P><P><SPAN>This interferogram shows permant ground movement/deformation due to the recent earthquakes.
