AbstractCanada, with its vast landmass, and diverse geography, geology and climate is exposed to many natural hazards. As populations and infrastructures continue to grow and develop, there is a greater need to know and understand the risk of these hazards. Assessing risks is key to the decision making process for emergency managers, land use planners and engineers. Natural Resources Canada (NRCan) in conjunction with collaborative partners, has started the adaptation of the US Federal Emergency Management Agency (FEMA) loss estimation tool Hazus for use in Canada. In 2011, NRCan signed a formal agreement with FEMA to share the methodology and outreach between the two agencies. Hazus is a best practice geospatial tool for estimating physical damage, economic and social losses from earthquakes, floods, and hurricanes; and will soon have a capability to estimate losses from tsunamis. Hazus and accompanying tools developed by NRCan are based on state-of-the-art scientific and engineering knowledge and provide a robust and standardized approach for estimating losses. Methods are being tested and evaluated through targeted case studies North Vancouver and Eastern Canada. The presentation examines the adaptation of the methodology and how capability is being built to address the needs and requirements of risk based decision makers in Canada.
Summary(Plain Language Summary, not published)
Natural Resources Canada is developing and adapting methods to evaluate earthquake risks to the community. Loss estimation methodologies, like HAZUS, and any other risk assessment tools require models that provide the vulnerability of buildings to earthquake actions, that is to say the expected level of damage or loss to buildings when subjected to specific seismic forces. Buildings vulnerability is expressed throughout Fragility Curves, which provide the probabilities of being in or exceeding some level or ¿damage state¿ conditional to an earthquake action. HAZUS is currently using fragility curves developed for California and the USA only. This document presents the initial steps and processes taken by Nat Res Can, to develop and adapt fragility curves useful for buildings in British Columbia to assess earthquake risks in the region.
