Earthquake Science, Hazards and Policy in Cascadia
The Cascadia Subduction Zone (CSZ) is the most densely populated subduction zone in the United States that is capable of producing megathrust earthquakes of approximately magnitude 9 (M9), yet its historical seismic quiescence contributes to its status as an “end-member” global subduction zone with respect to seismic activity. Recent years have brought a rapid increase in fundamental earthquake scientific knowledge about the region, through both observational studies such as the Cascadia Initiative, shoreline-crossing work, seafloor geodetic advancements and geophysical network buildout, as well as extensive geophysical modeling work. Recent projects such as the National Science Foundation-funded “M9 Project” have inspired integration of earthquake ground motion simulations with tsunami, ground failure and structural engineering studies, as well as social and behavioral sciences, planning and policy. Beyond these recent advances, Cascadia is home to large stakeholder companies involved in technological development and cloud computing infrastructure.
This session will highlight advances across earthquake hazards studies related to Cascadia earthquakes and their cascading hazards. We welcome submissions that fall within or across any of these categories, including both onshore and offshore observational and modeling work; geologic and geophysical earthquake studies in the CSZ; hazards-focused work including developments in earthquake recurrence, source physics, ground motion estimation, seismic hazard analyses, ground failure and tsunami studies; as well as social and behavioral sciences and planning studies related to the interpretation and application of recent scientific developments to quantify and reduce risk in the region.
