Surface Displacement Observations of the 2019 Ridgecrest, California Earthquake Sequence
Surface rupture associated with the 2019 Ridgecrest, California earthquake sequence includes the dominantly left-lateral and northeast-striking M6.4 rupture and dominantly right-lateral and northwest-striking M7.1 rupture. 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).
