What tectonic plate is located west of a trench which reaches a maximum-known depth of 10994 m?
Mariana Trench The Mariana Trench or Marianas Trench is the deepest part of the world's oceans. It is located in the western Pacific Ocean, an average of 200 km to the east of the Mariana Islands, in the Western Pacific East of Philippines. It is a crescent-shaped scar in the Earth's crust, and measures about 2550 km long and 69 km wide on average. It reaches a maximum-known depth of 10994 m (± 40 m ) at a small slot-shaped valley in its floor known as the Challenger Deep, at its southern end, although some unrepeated measurements place the deepest portion at 11034 m . If Mount Everest were dropped into the trench at this point, its peak would still be over 1.6 km underwater. In 2009, Marianas Trench was established as a United States National Monument.
Juan Fernández Ridge The Juan Fernández Ridge is a volcanic island and seamount chain on the Nazca Plate. It runs in a west-east direction from the Juan Fernández hotspot to the Peru–Chile Trench at a latitude of 33° S near Valparaíso. The Juan Fernández Islands are the only seamounts that reach the surface.
