AbstractWhile Canada is exposed to a variety of natural hazards, most risk and emergency managers lack the necessary tools and guidance to adequately undertake rigorous risk assessments. Recently, Natural Resources Canada - NRCan has adopted Hazus, a standardized best practice methodology and software for estimating potential losses from natural hazards (earthquakes, floods, and hurricanes) developed by the U.S. Federal Emergency Management Agency - FEMA. Integrated in GIS environment, Hazus includes large databases of hazard and inventory (exposure at risk). Damage and loss are predicted applying default or user provided damage curves which combine respective structural characteristics with the intensity of the natural hazard. An agreement has been signed with FEMA to adapt and co-develop Hazus for use in the Canadian context. At the same time, collaboration has been initiated within the federal government between the departments of Natural Resources, Environment, Defence and Public Safety to promote widespread usage of Hazus among the full range of Canadian decision makers. This technical note reports some of the typical features of the recently adapted Canadian version of the Hazus Earthquake model and resumes ongoing activities in implementing this model in Canada.
Summary(Plain Language Summary, not published)
It has been recognized that Canadian risk and emergency managers presently lack the necessary standardized tools and guidance to adequately undertake rigorous risk assessments. In the scope of respective mandates, NRCan has initiated collaboration with the departments of Environment, Defence and Public Safety to promote widespread usage of the U.S. FEMA's natural hazard risk assessment tool Hazus among the full range of Canadian decision makers. Hazus combines science, engineering knowledge, and mathematical modelling with geographic information systems technology (GIS) to estimate physical damage, economic and social losses. The earthquake model considers the following earthquake related hazards: ground shaking, landslides, liquefaction and fault rupture. Based primarily upon the intensity of the transient ground motion and the permanent ground deformation, four potential damage states are employed to estimate the amount structural damage and consequent economic and social losses.
