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

This work is done as part of the Metro Vancouver Seismic Microzonation Project which aims to improve our understanding of seismic hazards in the Georgia Basin and explore opportunities to reduce their impact through mitigation.Accurate shear wave velocity images of the subsurface is required to achieve this, hence 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.Here, we share a replication package that includes datasets (seismic and gravity), computer codes and scripts adopted and developed for this research work. The package also includes intermediate result files and final 3D models and GMT script used to plot each figure in the associated manuscript (Submitted to JGR Solid Earth). Our goal is to support research transparency and reproducibility of our work.
