This data set contains models of seismic (compressional- and shear-wave) velocity structure for the region surrounding the 2019 Ridgecrest, CA earthquake pair. These models were derived via traveltime tomography with the aftershock catalog that accompanies this data set (doi: 10.17632/x8v5wkbj6r.1). The models are discretized on a regular grid in geographical coordinates and shared in a single CSV file. The first three columns indicate the spatial position of the model parameters and the last two columns are the compressional- (or P-) and shear- (or S-) wave velocities in kilometers per second. White_et_al_2021__Rigecrest_2019_velocity.csv fields ============================================ - latitude: Node latitude in degrees - longitude: Node longitude in degrees - depth: Node depth (below sea level) in kilometers - vp: P-wave velocity in kilometers per second - vs: S-wave velocity in kilometers per second - vp/vs: Ratio of P- and S-wave velocities (unitless)
