This Earthquake Risk tool has been developed with the CoreLogic Canada Earthquake Model. The intent of this risk tool is to provide insights into the relative earthquake risk across Canada. This risk considers both the seismic hazard and population at risk in each region.

This ranking is reflective of the seismic hazard described by the Geological Survey of Canada (GSC) and US Geological Survey (USGS) for regions along the US border. Detailed soil maps and an understanding of the National Building Code of Canada and common building practices across the country are incorporated.

Population data from the 2011 Canada Census was used to represent the relative exposure at risk to seismic hazard by forward sorting areas (FSA) across the country. Discontinuities in relative risk were found in areas of very high hazard with corresponding very low exposure, such as high risk coastal regions of Vancouver Island. To account for this, an additional risk category has been added to reflect these regions of high hazard with low population.
