Stretching from northern California to the Salish Sea, the Cascadia coastline is a region of extraordinary natural and cultural richness, unique ecosystems, and significant risk. Located along the Pacific “Ring of Fire,” Cascadia sits above an active subduction zone and faces a range of coastal natural hazards: earthquakes, tsunamis, landslides, sea level rise, erosion, ecosystem changes, and the increasing impacts of climate change on storms and flooding severity.
