The Cascadia Subduction Zone | Making North America

Learn why an ancient earthquake that sunk a coastal rain forest into the tidal zone may portend a severe natural disaster in the Pacific Northwest today, in this video from NOVA: Making North America: Human. Use this resource to show evidence of past tectonic rupture and to visualize abstract concepts of plate movement and the resulting changes on Earth’s surface.
