Short Description | The California-Nevada Adjoint Simulations (CANVAS) model is a radially anisotropic adjoint waveform tomography model of the crust and uppermost mantle of California and Nevada. The model follows a multiscale inversion approach where we begin with a period band of 30-100 seconds and iterate down to a minimum period of 12 seconds over 161 iterations. Data from over 30,000 source-receiver pairs are used across 117 events. The model honors the Moho topography of Crust1.0 (Laske et al., 2013). |
