Phrase: Cascadia subduction zone | Statement: [Mount Meager massif, tectonicSetting, Cascadia subduction zone]

Target entity: Cascadia subduction zone
Context triple: [Mount Meager massif, tectonicSetting, Cascadia subduction zone]

• A. Cascadia Subduction Zone chosen
  The Cascadia Subduction Zone is a major convergent plate boundary off the Pacific Northwest coast of North America, capable of generating powerful megathrust earthquakes and tsunamis.
• B. 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.
• C. Juan de Fuca Ridge
  Juan de Fuca Ridge is an underwater volcanic spreading center in the northeastern Pacific Ocean where new oceanic crust forms as tectonic plates diverge.
• D. Nootka Fault
  Nootka Fault is a major transform fault off the coast of British Columbia that separates segments of the Explorer Plate and plays a key role in the tectonics of the Cascadia subduction zone.
• E. 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.
