Abstract
Evidence based on radiometric age dating and site investigation suggests that the Ottawa region experienced two geologically destructive earthquakes. One, at 4550 yr B.P., caused widespread landsliding in sensitive marine clays. The other, at 7060 yr B.P., caused irregular surface subsidence, lateral spreading, and sediment deformation in thick deposits of marine clay and sand infilling a small deep bedrock basin. Magnitude of these earthquakes probably exceeded 6.5.
