The city of Ottawa lies in the active seismic zone of Western Quebec. Significant earthquake hazards exist in this zone and in Eastern Canada. It was in this zone that the 1935 Temiskaming earthquake, magnitude M6.2, and the 1944 Cornwall-Massena earthquakes, magnitude M5.8, occurred. The phenomenon of seismic soil amplification by soft sediments has been observed in several locations in the Ottawa region and studied by researchers. Their findings highlight the potential of Ottawa soils for very large amplifications, at least for weak motions.

渥太华市位于魁北克西部的活跃地震区。该地区和加拿大东部存在严重的地震灾害。1935年的特米斯卡明6.2级地震和1944年的康沃尔-马塞纳5.8级地震就是在这个地区发生的。研究人员在渥太华地区的几个地点观察到了软土地震放大现象，并对其进行了研究。他们的发现突出了渥太华土壤的潜力，可以进行非常大的放大，至少可以进行微弱的运动。
