Development of regional site amplification models for eastern canada

蒙特利尔和渥太华位于活跃的魁北克西部地震带，这使它们面临地震危险。潜在的风险最近在2010年6月23日发生的5.0级地震中突显出来，该地震位于渥太华市东北约50公里处。这场地震在渥太华位于软冰期后沉积物上的地区有强烈的震感，这放大了地震震动的程度。土壤放大可以显著影响地震事件的地面运动和危害；最新版本的加拿大国家建筑规范(2005)认识到它的重要性，采用地震场地分类系统来确定土壤放大系数。

The location of Montreal and Ottawa in the active Western Quebec seismic zone places them at risk of seismic hazards. The potential risk was recently highlighted with the magnitude M5.0 earthquake on June 23, 2010, located about 50 km northeast of the city of Ottawa. This earthquake was felt strongly in areas of Ottawa that are located on soft postglacial sediments, which amplified the level of earthquake shaking. Soil amplification can significantly influence the ground motions and hazards of seismic events; and, the most recent version of the National Building Code of Canada (2005) recognizes its importance with a seismic site classification system to determine soil amplification factors.
