Optical satellite observations were used to quantify ground-surface displacements resulting from the 2019 Ridgecrest, California, earthquakes. Specifically, optical images from WorldView-1, WorldView-2, and WorldView-3 collected before and after the 2019 Ridgecrest earthquakes were accessed via the ©NextView license. These data were processed and analyzed to calculate three-dimensional displacements resulting from the M6.4 and M7.1 strike-slip faulting earthquakes. These results show that peak lateral displacement was more than 1 meter and more than 4.5 meter for the M6.4 and M7.1 earthquakes, respectively. Initial rapid results were published in Geophysical Research Letters. A more detailed manuscript and associated data release with the entire processed dataset is currently in review. This project represents a collaboration between the USGS and academic partners at the University of Iowa and Université Grenoble Alpes (France).
