The Cascadia Subduction Zone: Grand Challenges and Research Frontiers
Subduction zones generate the world’s largest earthquakes. Their strong shaking and related cascading hazards such as tsunamis, landslides, liquefaction, fire, etc., make them the source of some of the most devastating natural hazards. The Cascadia Subduction Zone (CSZ), spanning three states in the U.S. and British Columbia in Canada, is such a hazardous system and at the same time represents one of the world’s best natural earthquake laboratories. While the Cascadia megathrust is seismically quiet compared to many other subduction zones, fundamental discoveries on phenomena including slow slip and tremor have shown it to be a hub of tectonic activity. Moreover, the region hosts one of the most comprehensive geologic records of past great earthquakes. Research involving the CSZ has yielded some of the most intriguing recent advances in the physics and impacts of earthquakes, and, fresh ideas and future scientific endeavors are required to foster and accelerate this progress.
