AbstractA comprehensive seismic risk assessment study was completed in the Ottawa and St. Lawrence valleys, Canada, with the objective to provide emergency managers with necessary knowledge for informed decision making. Earthquake related geohazards were investigated divided into transient ground motion and permanent ground deformation. Characteristic earthquake scenarios were defined using the combination of ground motion prediction equation to determine the intensity of bedrock shaking. Amplification factors with respect to the shear wave velocity of the top 30 m were defined to determine the spatial distribution of the ground shaking. The landslide and liquefaction potentials were studied using regional proxies.
Summary(Plain Language Summary, not published)
Earthquake related geohazards were investigated in the Ottawa and St. Lawrence valleys, Canada. Two types of seismic hazards were considered: transient ground motion and permanent ground deformation. Shake Maps spatial distribution of earthquake shaking and landslide and liquefaction susceptibility were generated as the necessary input for successive assessment of negative impacts.
