Shapefile of Fault Rupture and Ground Deformation Features Produced by the Ridgecrest M6.4 and M7.1 Earthquake Sequence of July 4 and 5, 2019: Provisional Release 1

This item contains linework that represents fault rupture and ground deformation features interpreted from field-based maps and observations, as well as airborne imagery, lidar, and geodetic imagery products. Provisional maps of fault rupture and ground deformation are composed of a “mashup” of linework from these various sources, obtained and compiled as of December, 2019. If more than one linework representation exists for a segment of the fault rupture, linework showing the most rupture detail or best location accuracy, based on the judgment of the compiler, is preserved. On provisional maps, less than 25% of the linework is derived from high-resolution optical imagery and detailed field mapping. Because line segments from the various sources vary in location accuracy and precision based on the source equipment or imagery, mismatches can occur at the boundaries between linework from different sources. No corrections are made for these mismatches in the provisional maps. Final maps will reconcile all linework to a single registered base map
