Phrase: Cascadia subduction zone | Statement: [Mount Callaghan, tectonicSetting, Cascadia subduction zone]

Target entity: Cascadia subduction zone
Context triple: [Mount Callaghan, tectonicSetting, Cascadia subduction zone]

• A. Cascadia Subduction Zone chosen

  The Cascadia back-arc region is a tectonically active area east of the Cascadia subduction zone characterized by crustal extension, volcanism, and associated magmatic and geothermal activity.
• D. Mariana subduction zone
  The Mariana subduction zone is a deep oceanic trench system in the western Pacific where the Pacific Plate is forced beneath the smaller Mariana Plate, creating one of the world's deepest and most active tectonic boundaries.
• E. Pacific–Juan de Fuca plate boundary
