The Multi-Scale CALifornia (MSCAL) statewide velocity model provides a high-resolution, integrated description of seismic structure across the state. Built upon the CANVAS base model (Doody et al., 2023), MSCAL incorporates diverse regional and local velocity datasets into a unified structure, capturing features ranging from broad crustal-mantle structures to fine-scale local anomalies such as sedimentary basins. To ensure performance, the model underwent a data-informed refinement process guided by simulations of small validation events. A key feature of MSCAL is the inclusion of a spatially-optimized near-surface low-velocity taper (LVT), specifically designed to better represent under-resolved shallow structures and improve the accuracy of ground-motion predictions.
