Target entity: Kermadec-Tonga subduction system
Context triple: [Kermadec Trench, geologicalProvince, Kermadec-Tonga subduction system]
  • A. Tonga-Kermadec subduction system chosen
    The Tonga-Kermadec subduction system is a major convergent plate boundary in the southwest Pacific where the Pacific Plate descends beneath the Indo-Australian Plate, producing one of the world’s deepest ocean trenches and most active seismic and volcanic regions.
  • B. Sunda subduction system
    The Sunda subduction system is a major convergent plate boundary in Southeast Asia where the Indo-Australian Plate is being subducted beneath the Eurasian/Sunda Plate, generating intense seismic and volcanic activity along Indonesia’s island arcs.
  • C. 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.
  • D. Kuril–Kamchatka subduction system
    The Kuril–Kamchatka subduction system is a major convergent plate boundary in the northwest Pacific where the Pacific Plate subducts beneath the Okhotsk Plate, generating intense seismic activity and extensive volcanism along the Kuril Islands and Kamchatka Peninsula.
  • E. Tonga–Kermadec Arc
    The Tonga–Kermadec Arc is a major submarine volcanic island arc and trench system in the southwest Pacific Ocean, formed by the subduction of the Pacific Plate beneath the Indo-Australian Plate and known for its intense seismic and volcanic activity.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
