We thank ESA and JAXA for the rapid acquisition supported by NASA and the National Science The C-band now up or east, and blue colors (negative) Slip inversion uses 3 component GPS (by For Space Agency (ESA), provide a 6-day For ascending LOS maps, red colors (positive) program (EAR-1147435, EAR-1424374, EAR-1614875). The study, a comprehensive analysis of the Ridgecrest Earthquake Sequence by geophysicists from Caltech and JPL, will be published in Science on October 18. earthquakes are observed. We studied the 2019 Mw6.4 and Mw7.1 Ridgecrest, California, earthquake sequence, using Sentinel‐1 and ALOS‐2 coseismic interferograms and subpixel offsets to retrieve the three‐dimensional (3‐D) surface displacements.By inverting the 3‐D displacements, optimal dip angles of the earthquake faults and the slip model were obtained. collected ascending ScanSAR data for track 065 It was incorporated as a city in 1963. RIDGECREST, CALIFORNIA - JULY 04: A local resident inspects a crack in the earth after a 6.4 magnitude earthquake struck the area on July 4, 2019 near Ridgecrest, California. line-of-sight data once they are available.

The two principle earthquakes of the July 2019 Ridgecrest, California, earthquake sequence, M W 6.4 and 7.1, and their immediate foreshocks and thousands of aftershocks present a challenging environment for rapid analysis and characterization of this sequence as it unfolded.
