Philippine subduction system

Target entity: Philippine subduction system
Context triple: [East Luzon Trough, isPartOf, Philippine subduction system]

• A. 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.
• B. 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.
• C. 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.
• D. Aleutian subduction system
  The Aleutian subduction system is a major tectonic plate boundary where the Pacific Plate is forced beneath the North American Plate, forming the Aleutian Trench and associated volcanic island arc in the North Pacific.
• E. Southwest Pacific tectonic system
  The Southwest Pacific tectonic system is a complex network of interacting tectonic plates, subduction zones, trenches, and volcanic arcs that shapes the geologic and seismic activity of the southwest Pacific region.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: Philippine subduction system
Target entity description: The Philippine subduction system is a complex convergent plate boundary zone around the Philippine Sea Plate, characterized by multiple trenches, active subduction, frequent earthquakes, and volcanism.
