Where is the deepest ocean trench created by earthquakes and subduction?

Quick Answer

The deepest known ocean trench is the Mariana Trench in the western Pacific Ocean, east of the Mariana Islands. Its deepest point is the Challenger Deep.

The Full Story

The Mariana Trench forms where the Pacific Plate is being forced beneath the smaller Mariana Plate. This subduction creates intense earthquakes and the deepest seafloor depression on Earth. Challenger Deep, in the southern part of the trench, is commonly cited at around 10,900 to 11,000 meters below sea level. Because of its depth and pressure, it is one of the most extreme environments on the planet.
