Urban Seismic Risk
Urban seismic risk is a subset of the general term seismic risk which describes the problems specific to centers of population when they are subjected to earthquakes. Many risks can be minimized with good earthquake construction, and seismic analysis. One of the best ways to deal with the issue is through an earthquake scenario analysis. Toronto Toronto, Ontario, Canada is used as an example city in this article. The general issues are common to all cities subject to earthquakes. Cities are a mixture of old and new construction as in this picture. Note the old brick building mixed in with the new highrises, and the famous Toronto CN Tower. Similar to methodologies used in nuclear reactors, a seismic walk down of the city is the best way to identify vulnerabilities and possible places for improvement. Toronto is located on the shores of Lake Ontario, the site of much microseismicity. Historic records indicate that energetic earthquakes occur infrequently in the region, as ...
