Ridgecrest, CA seismic velocity models

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, the second set of three columns indicate the compressional- (or P-) and shear- (or S-) wave velocities (Vp and Vs , respectively) in kilometers per second and their ratio (Vp/Vs), and the last three columns indicate the uncertainties associated with each of these values.
