Earthquake Ground Motions and Structural Response in Subduction Zones: A Focus on Cascadia
Date: 4/24/2019
Time: 8:30 AM to 3:30 PM
Room: Pine
Accurate estimates of earthquake ground motions and structural response in subduction zone settings are critical to improving seismic hazard assessment and community resilience. This is especially true in the Cascadia subduction zone, with its susceptibility to multiple types of earthquake sources (e.g., megathrust, crustal and intraslab), the presence of deep sedimentary basins and proximity to major cities such as Portland, Oregon; Seattle, Washington and Vancouver, British Columbia.
We invite studies focusing on ground motion estimates using a variety of seismological approaches (e.g., observational, theoretical, numerical modeling), as well as those that assess the response of man-made structures and the underlying local site due to earthquake ground motions. We welcome results from all subduction zone systems, with a particular focus on those that may improve our understanding of seismic hazard in Cascadia.
