Cascadia Map

The Cascadia Map is a geological model that illustrates the likelihood and potential pathways of a major earthquake along the Cascadia Subduction Zone, which runs off the Pacific Northwest coast. It highlights areas at risk of shaking, uplift, and tsunamis during a significant seismic event. The map combines scientific data on fault lines, historical earthquake patterns, and ground movement to help communities prepare for possible scenarios. Its goal is to inform resilient planning and encourage readiness for one of North America’s most powerful and potentially destructive earthquake zones.
