This data release includes surface-displacement observations of these ruptures made by teams of federal, state, academic, and private sector geologists between July and November 2019. These displacement observations describe laterally and/or vertically displaced cultural and geomorphic features. Displacement data included in this release are a subset of observations included in a Seismological Society of America Data Mine article (Ponti et al., in review). Our intent is to compile a complete set of field measurements for the M6.4 and M7.1 ruptures for the purpose of evaluating patterns of surface displacement along fault strike. In evaluating the original data, we synthesized duplicate and repeated measurements at a site, excluded some measurements with insufficient documentation or based on compiler judgement, and combined some measurements across zones of complex faulting (e.g., including summed measurements for subparallel fault strands). Additional discussion of these data is included in a companion journal article (DuRoss et al., in press, Bulletin of the Seismological Society of America). To provide field observations of surface displacement measured following the 2019 Ridgecrest, California earthquake sequence. 20190704 20191130 Data acquisition Complete Unknown -117.8641 -117.4081 35.9310 35.4849 USGS Thesaurus Earthquake Fault Displacement USGS Metadata Identifier USGS:5e7e79afe4b01d50927718a1 GNIS Ridgecrest China Lake Salt Wells Valley California none none Christopher B.

Users are advised to read the rest of the metadata record carefully for additional details. No formal positional accuracy tests were conducted No formal positional accuracy tests were conducted Field-based measurements of displacement were collected using various methods including tape measurements and high-precision GPS surveys. These data were evaluated and compiled into displacement datasets for the M6.4 and M7.1 Ridgecrest earthquake ruptures. 2020 Location coordinates provided in WGS84 UTM zone 11 Point Universal Transverse Mercator 11 0.9996 -117.0 0.0 500000.0 0.0 coordinate pair 1.0 1.0 meters Data tables (M6.4_Curated_disp_v1.txt and M7.1_Curated_disp_v5.txt) Surface-displacement measurements Producer conceived Slip_Sense Fault slip sense. 1 = right-lateral, 2 = left-lateral, 3 = vertical Producer defined 1 3 Strand Fault strand number.
