Development of regional site amplification models for eastern canada

蒙特利尔和渥太华位于活跃的西魁北克地震带，这使它们面临地震危险。2010年6月23日，渥太华市东北约50公里处发生了里氏5.0级地震。这次地震在渥太华的一些地区有强烈的震感，这些地区位于软的冰川后沉积物上，这加剧了地震的震动程度。土壤放大对地震动和地震事件的危险性有显著影响；而且，最新版本的加拿大国家建筑规范（2005年）认识到它在地震场地分类系统中确定土壤放大系数的重要性。

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.
