Plate Tectonics: Seafloor Spreading, Subduction and Megathrust Earthquakes

n this video an introduction to seafloor spreading, subduction and megathrust earthquakes are animated to allow for easier understanding of the topics. The Cascadia Subduction Zone is used as the example. An area where the Juan de Fuca plate is being subducted under the North American Plate. We use images that can be found on our World Satellite Map.
