Target entity: Sunda subduction system
Context triple: [Java Trench, tectonicProvince, Sunda subduction system]
  • A. Sumatra subduction zone
    The Sumatra subduction zone is a major convergent plate boundary off the western coast of Sumatra where intense seismic and volcanic activity occurs, including some of the world’s largest recorded earthquakes and tsunamis.
  • B. Tonga-Kermadec subduction system
    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.
  • C. 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.
  • 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. Hellenic subduction system
    The Hellenic subduction system is a major convergent plate boundary in the eastern Mediterranean where the African Plate is being subducted beneath the Aegean microplate, creating deep-sea trenches, intense seismicity, and active volcanism.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
