AbstractWhile Canada is exposed to a variety of natural hazards, most risk and emergency managers presently lack the necessary tools and guidance to adequately undertake rigorous risk assessments. Recently, Natural Resources Canada - NRCan has adopted Hazus, a standardized methodology for estimating potential losses from natural hazards developed by the U.S. Federal Emergency Management Agency - FEMA (fema.gov/hazus), as one of the best practice methods for risk assessment. By natural hazards are understood hazards such as earthquakes, floods, and hurricanes. The methodology comprises three major components: hazard, assets at risk (inventory), and vulnerability. The natural hazard component is defined with the spatial distribution of its intensity over the study area and over a given period of time; the assets at risk consider the build environment, infrastructure and population vulnerable to the given hazard; whereas the vulnerability reflects the susceptibility to hazard impacts - negative effects and is defined with expected degree of physical damage, and social and economic losses. This technical note reports the typical features of the Canadian version of the Hazus model and resumes ongoing activities and potential challenges in implementing this model in Canada.

While Canada is exposed to a variety of natural hazards, most risk and emergency managers presently lack the necessary tools and guidance to adequately undertake rigorous risk assessments. Recently, Natural Resources Canada - NRCan has adopted Hazus, a standardized methodology for estimating potential losses from natural hazards developed by the U.S. Federal Emergency Management Agency - FEMA. Considered natural hazards are earthquakes, floods, and hurricanes. The methodology comprises three major components: hazard, assets at risk (inventory), and vulnerability. The natural hazard component is defined with its intensity over a given period of time; the assets at risk consider the build environment and population; whereas the vulnerability is defined with expected degree of damage, social and economic losses.
