Regional Accessibility of Post-Earthquake Emergency Healthcare in Metro Vancouver, BC

The system under investigation is the regional network of emergency healthcare facilities and transportation infrastructure in Metro Vancouver, British Columbia. This dataset was developed to support a regional assessment of healthcare accessibility following a major earthquake hazard, specifically under a suite of physics-based Cascadia Subduction Zone (CSZ) M9 earthquake scenarios. The dataset integrates spatial information on hospitals with emergency departments, bridges, and the regional road network, along with estimated seismic damage states for healthcare and bridge assets based on seismic fragility analysis.

The data address the research problem of quantifying how earthquake-induced physical damage affects access to critical medical services. Hospital functionality and bridge performance are combined with accessibility metrics based on the Enhanced Two-Step Floating Catchment Area (E2SFCA) method to evaluate system-level interdependencies and spatial variations in emergency healthcare availability after an earthquake.

The dataset can be reused to reproduce or validate regional accessibility assessments or incorporate information for multi-hazard assessments of regional infrastructure. The data are valuable for researchers, infrastructure planners, and emergency management professionals seeking to improve the resilience of interconnected health and transportation systems. All documentation required for use of the data set is included in the Data Report.
