S1A: Cascadia Earthquake Disaster Risk Reduction

Despite evidence of past large M8-9 earthquakes in the Cascadia Subduction Zone (CSZ), e.g., native oral histories and paleoseismic records, there are no seismic recordings of ground shaking during these events. How the CSZ will rupture in an inevitable future megathrust earthquake and its impacts on the built environment and communities along the Cascadia corridor are largely unknown. As such, there are substantial opportunities for comparative and collaborative research of global significance that spans the natural, social, engineering, public health, and policy sciences. This session will serve as a platform to showcase ongoing research that advances both fundamental knowledge, as well as science and engineering technology, to support the resilience of communities across the Cascadia region. The session will address three subtopics: (1) Seismic Hazard, (2) Impacts on the Built Environment and (3) Community Resilience.
