Entity: Mariana subduction zone
Triple: [Mariana volcanic arc, overlies, 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.
