Target entity: Middle America subduction zone
Context triple: [Cocos–North America plate boundary, partOf, Middle America subduction zone]
  • A. Cascadia Subduction Zone
    The Cascadia Subduction Zone is a major convergent plate boundary off the Pacific Northwest coast of North America, capable of generating powerful megathrust earthquakes and tsunamis.
  • B. 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.
  • C. Cascadia back-arc region
    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. Middle America Trench subduction interface chosen
    The Middle America Trench subduction interface is a major convergent plate boundary off the Pacific coast of Central America and Mexico where the Cocos Plate is forced beneath the North American and Caribbean Plates, generating powerful megathrust earthquakes.
  • E. Cocos–North America plate boundary
    The Cocos–North America plate boundary is a convergent tectonic margin where the oceanic Cocos Plate subducts beneath the continental North American Plate, generating significant seismic and volcanic activity along Mexico’s Pacific coast.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
