Phrase: subducting Rivera Plate | Statement: [Jalisco Block, overlies, subducting Rivera Plate]

Target entity: subducting Rivera Plate
Context triple: [Jalisco Block, overlies, subducting Rivera Plate]

• A. 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.
• B. Hikurangi subduction margin
  The Hikurangi subduction margin is a major plate boundary off the east coast of New Zealand’s North Island where the Pacific Plate is being subducted beneath the Australian Plate, driving significant seismic, volcanic, and geothermal activity.
• C. Andean subduction system
  The Andean subduction system is a major tectonic convergent margin along western South America where an oceanic plate descends beneath the continent, driving Andean mountain building, volcanism, and seismic activity.
• D. 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.
• E. 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.
