Are buildings designed to withstand earthquakes in Canada?
The first seismic hazard maps for use in Canada have been in use since 1953. This initial hazard map was a subjective assessment based on historical seismicity. In 1970 the first modern maps were developed using probabilistic methods. In 1985 two maps were produced, “acceleration” – suitable for use when designing small structures, and “velocity” – suitable for use when designing large structures. New maps are nearing completion and are available here.
