Southwest Pacific tectonic system

Target entity: Southwest Pacific tectonic system
Context triple: [New Guinea Trench, partOf, Southwest Pacific tectonic system]

• A. East Pacific tectonic system
  The East Pacific tectonic system is a major geological region in the eastern Pacific Ocean characterized by active seafloor spreading, transform faults, and subduction zones that shape the surrounding oceanic plates and continental margins.
• 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. 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.
• D. Pacific Plate fracture zone system
  The Pacific Plate fracture zone system is a network of major undersea tectonic fractures and transform faults that segment and shape the Pacific Plate across the ocean floor.
• E. Banda Sea subduction system
  The Banda Sea subduction system is a complex convergent plate boundary in eastern Indonesia where oceanic lithosphere descends beneath surrounding plates, generating intense seismicity, volcanism, and intricate arc-continent collision structures.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
