Replication Package: 3D Shear‐wave Velocity and Density Modelling of the Northern Cascadia Subduction Zone

To enhance the accuracy of seismic hazard assessments and ground motion simulations within the Northern Cascadia Subduction Zone (NCSZ), we developed a new 3D shear-wave velocity (Vs) model for the region from ambient seismic noise and earthquake data recorded by temporary and permanent seismic stations in the last two decades as well as a new 3D density model from a publicly available gravity dataset.<br><br>This is a replication package that includes information about the datasets (seismic and gravity) used, computer codes and scripts developed for this work and resulting 3D model files and images. The goal is to support research transparency and reproducibility of our work.
