    This geology image could be re-created using vector graphics as a SVG file. This has several advantages; see Commons:Media for cleanup for more information. If a SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}.
    It is recommended to name the SVG file “Cascadia subduction zone USGS.svg”—then the template Vector version available (or Vva) does not need the new image name parameter.
