| Abstract | Numerous computer models have been developed for seismic loss analyses at urban and regional scales. They seem, however, ill-suited to custom application to the specific Canadian hazard and exposure
settings and, more importantly, inadequate for utilization by the broader non-expert public safety community. Therefore, communication of the potential seismic risk results to local stakeholders, such that they can properly understand their exposure
and vulnerability, represents an outstanding challenge. The objective of the present study is to describe the methodological background and ongoing development activities of the Rapid Risk Evaluator (ER2), a relatively rapid and user-friendly risk
assessment application, developed to overcome the current communication barriers between risk experts and decision makers. Developing ER2 included: pre-computing site-specific databases containing ground motion scenarios, prediction of potential
attenuation with distance and local site amplification, a standardized inventories of buildings' structural properties and occupancy categories, and assessment of the seismic vulnerability using hazard-compatible vulnerability functions. These
functions correlate directly the intensity of the seismic shaking to the probability of damage and direct economic and social losses. This approach allows for conducting risk scenarios in large urban centers within minutes. The above approach was
programmed into an easy to run web-application. Equipped with graphic user interface, ER2 allows non-expert users to run otherwise complex seismic risk scenarios through a simple intuitive selection process. An example of ER2 applied to a
hypothetical earthquake event in Quebec City is included to illustrate the simplicity of the user interface and capabilities of the application. |
