The Mariana Trench (or Marianas Trench) is the deepest known submarine trench, and the deepest location in the Earth's crust itself. It is located in the floor of the western North Pacific Ocean, to the east of the Mariana Islands at 11° 21' North latitude and 142° 12' East longitude, which is near Japan.
