District of North Vancouver Case Study

Hazus Canada Case Study - West Coast Earthquake Loss Assessment

The Vancouver Office of Natural Resources Canada working on the Quantifying Geohazard Risk Project is demonstrating the application of Hazus Canada earthquake module in a case study for the West Coast.

Synopsis of Earthquake Risk Assessment for the District of North Vancouver

Overview: Based on input from DNV Natural Hazard Task Force members and consultations with domain experts in the field we have adopted a hybrid approach to modeling earthquake risk at the community scale. In accordance with safety threshold guidelines of the 2010 National Building Code for Canada (NBCC; http://www.earthquakescanada.nrcan.gc.ca/hazard-alea/zoning-zonage/haz-eng.php), we are using probabilistic ground motions that have been estimated for a recurrence interval of 1/2475 years (2% in 50 years) to identify individual community assets that are likely to be vulnerable to physical damages from all know earthquake sources in the region. In accordance with best practice guidelines for North America (http://www.nehrpscenario.org), we are using deterministic ground motions for a representative set of event scenarios to assess the aggregate risks associated with a specific earthquake, and to explore risk reduction and disaster resilience planning strategies.
