Development of regional site amplification models for eastern canada

蒙特利尔和渥太华位于魁北克省西部地震活跃带，面临地震危险。最近，2010 年 6 月 23 日发生在渥太华市东北约 50 公里处的 M5.0 级地震凸显了潜在的风险。渥太华位于松软的冰期后沉积物上的地区对这次地震有强烈的震感，从而加剧了地震的震动程度。土壤放大可以显着影响地震事件的地面运动和危害；而且，最新版本的加拿大国家建筑规范（2005 年）认识到地震站点分类系统在确定土壤放大系数方面的重要性。

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.
