There are about 50,000 km (31,000 mi) of oceanic trenches worldwide, mostly around the Pacific Ocean, but also in the eastern Indian Ocean and a few other locations. The greatest ocean depth measured is in the Challenger Deep of the Mariana Trench , at a depth of 10,994 m (36,070 ft) below sea level .
Location of the Mariana Trench. The Mariana Trench is an oceanic trench located in the western Pacific Ocean, about 200 kilometres (124 mi) east of the Mariana Islands; it is the deepest oceanic trench on Earth. It is crescent-shaped and measures about 2,550 km (1,580 mi) in length and 69 km (43 mi) in width.

The trench is 1,700 miles (2,750 km) long and is 21,880 feet (6,669 m) at its deepest point. The trench is the boundary between the Rivera, Cocos, and Nazca plates on one side and the North American and Caribbean plates on the other. It is the 18th-deepest trench in the world.
The Izu–Ogasawara Trench (伊豆・小笠原海溝, Izu–Ogasawara Kaikō), also known as Izu–Bonin Trench, is an oceanic trench in the western Pacific Ocean, consisting of the Izu Trench (at the north) and the Bonin Trench (at the south, west of the Ogasawara Plateau). [1] It stretches from Japan to the northernmost section of Mariana ...
The Mariana Trench is the deepest known submarine trench, and the deepest location in the Earth's crust itself. [38] It is a subduction zone where the Pacific Plate is being subducted under the Mariana Plate. [3] At the deepest point, the trench is nearly 11,000 m deep (almost 36,000 feet).
Map of the Zealandia continent that shows the Hikurangi Margin as a red dotted line arising from the Chatham Rise, New Zealand intersection. The Hikurangi Trough (previously known as the Hikurangi Trench) [1] [a] is a sea floor feature of the Pacific Ocean off the north-east South Island and the east coast of the North Island of New Zealand.
The Tonga Trench is an oceanic trench located in the southwestern Pacific Ocean. It is the deepest trench in the Southern hemisphere and the second deepest on Earth after the Mariana Trench . The fastest plate-tectonic velocity on Earth is occurring at this location, as the Pacific plate is being subducted westward in the trench.
