Disrupted transportation networks in a plausible megathrust earthquake scenario on Canada’s West Coast
Canada’s West Coast is located near the Cascadia Subduction Zone, a region susceptible to high-magnitude earthquakes. The database describes the multi-modal transportation network and its expected disruptions in a plausible Cascadia Subduction Zone earthquake scenario, considering two cases: a medium and a high impact. The main elements of the regional transportation network are the roads, maritime and air routes and infrastructures, and communities. Their respective data are organized in the files included in this dataset. The road data include the distances of the road segments, their trajectories in terms of geographic coordinates, and expected damage levels. The maritime transportation data describe the available vessels, their capacities, trajectories, and expected delays. The geographic coordinates of the ports in the study area are also included. The air transportation data includes the coordinates of airports, heliports, and helipads, and the geodesic distances to the communities. The location of the communities, their population size and their expected impact level are included as well. The data is a combination of the results generated by application of several impact models with openly available reports, and external datasets.
