Includes bibliographical references (p. 7). “Canada’s 3rd Generation seismic hazard model was the basis for the seismic design provisions in the 1985, 1990, and 1995 National Building Codes of Canada. These codes use best-estimate ground motion on firm soil sites for a probability of exceedance of 10% in 50 years. The ground motion was quantified by seismic hazard values for two parameters: peak acceleration and peak velocity. For consistency with our later products, we tabulate code values of the two parameters for more than 200,000 grid points over Canadian territory and surrounding areas. Values at four probability levels ranging from 1 in 100 to 1 in 1000 years are also provided which allows for the construction of 3rd Generation hazard curves for every locality in Canada. The information retroactively comprehensively documents the basis for earthquake-resistant design for buildings constructed according to the requirements of the 1985 to 1995 codes, and may prove useful in structural retrofit decisions”--Abstract, p. 2.
