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

Development of 3D shear-wave velocity (Vs) and density models of southwest British Columbia and Washington State are accomplished as part of the Metro Vancouver Seismic Microzonation Project (MVSMMP) which aims to improve understanding of seismic hazards in the Georgia Basin.

The 3D Vs model is developed from ambient seismic noise and earthquake data recorded by temporary and permanent seismic stations in the last two decades. A 3D density model is also developed 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 Ojo et al. (2025) JGR Solid Earth article. Our goal is to support research transparency and reproducibility of our work.
