In this system, the western edge of one plate, the Pacific Plate, is subducted (i.e., thrust) beneath the smaller Mariana Plate that lies to the west.
Located in the western Pacific east of the Philippines and an average of approximately 124 miles (200 kilometers) east of the Mariana Islands, the Mariana Trench is a crescent-shaped scar in the Earthâs crust that measures more than 1,500 miles (2,550 kilometers) long and 43 miles (69 kilometers) wide on average.hallenger II returned to the spot with an echo-sounder and measured a depth of nearly 7 miles (11 kilometers). The majority of the Mariana Trench is now a U.S. protected zone as part of the Marianas Trench Marine National Monument, established by President George W. Bush in 2009.
