The deepest points on earth are found in various parts of the seas on earth; the deepest points have been discovered and are continually being investigated by explorers; nevertheless, there may be unknown or unexplored deepest points on earth other than the Mariana Trench, which is the deepest point on the planet. Oceanic trenches are long, narrow topographic cavities on the seafloor that extend to the ocean’s deepest regions.

The Pacific Ocean features around 50,000 kilometers of convergent plate boundaries, with the majority of the deepest points found near this location. Geographical activity carved deep tunnels beneath the ocean, some of which might be thousands of feet deep. The Pacific and Atlantic Oceans are the world’s deepest oceans.

10. Atacama Trench

The Atacama Trench, commonly known as the Peru-Chile Trench, is roughly 5,900 kilometers long and 64 kilometers wide, covering around 590,000 square kilometers. A convergent boundary defines the border between the subducting Nazca Plate and the South American Plate, resulting in the trench.

Maximum depth: 8,065 meters
Location: Eastern Pacific Ocean, about 160 km off the coast of Peru and Chile.

9. South Sandwich Trench

Subduction creates a deep arcuate trench in the South Atlantic Ocean, which is the deepest trench in the Southern Atlantic Ocean. The South Sandwich Islands form a volcanic island arc along the trench, resulting from Mount Belinda’s active volcano and Montagu Island.

Maximum depth: 8,428 meters
Location: 55°40’S, 025°55’W, 122km northeast of Zavodovski Island

8. Puerto Rico Trench

The trench is located on the Atlantic Ocean’s border with the Caribbean Sea. There is an earthquake in the area, which might result in a large tsunami. The trench is 800 kilometers long, with the deepest point being found in Milwaukee Deep, as well as the Atlantic Ocean’s deepest point.

Maximum depth: 8,648 meters
Location: Between the Caribbean Sea and the Atlantic Ocean

7. Japan Trench

It’s part of the Pacific Ring of Fire, which stretches across the northern Pacific Ocean off the coast of northeast Japan and is thought to be formed when the oceanic Pacific Plate subducts beneath the continental Okhotsk Plate. Tsunamis and earthquakes are the important cause of the Japan Trench’s subduction zone migration.

Maximum depth: 9,000 meters
Location: between the Kuril Islands and Bonin Islands, northern Japan, Pacific Ocean

6. Izu-Ogasawara Trench

It is located in the western Pacific Ocean, stretching from Japan to the north, as well as the extent of the Japan Trench, where the Pacific plate is subducted beneath the Philippine Sea plate, resulting in the formation of the Izu Islands and Bonin Islands.

Maximum depth: 9,780 meters
Location: South of Japan, Western Pacific Ocean.

5. Kermadec Trench

It’s formed by the Pacific plate beneath the Indo-Australian Plate over hundreds of kilometers parallel to the island arc, and it’s known for its steep slope. Deep-sea researchers made the first descents into the trench in 2012, discovering new species of gigantic amphipod.

Maximum depth: 10,047 meters
Location: South of Japan, Western Pacific Ocean.

4. Kuril–Kamchatka Trench

Also known as the Kuril trench formed as a result of the late Cretaceous that created a Kuril island arc and the volcanic arc. The zone is located off the southeast coast of Kamchatka and is the site of a significant earthquake that happened in recent decades.

Maximum depth: 10,500 meters
Location: Off the southeast coast of Kamchatka, northwest Pacific Ocean.

3. Philippine Trench

The Philippine trench’s deepest point named the Galathea Depth, the world’s third deepest trench, is 1,320 kilometers long and 30 kilometers broad and is located in the Philippines’ east. This is caused by tectonic plate collisions, and the Philippine Sea is subducting at a rate of 16cm per year beneath the Philippine Mobile Belt.

Maximum depth: 10,540 meters
Location: Northern Maluku island of Halmahera in Indonesia.

2. Tonga Trench

The Horizon Deep in the Tonga Trench, the second deepest point on Earth, is located at the northern extremity of the Kermadec Tonga Subduction Zone and stands alone in the South Pacific Ocean. The tonga runs north-northeast from the Kermadec Islands, just north of New Zealand’s North Island.

Maximum depth: 10,882 meters
Location: 4500 from the center of Australia, South Pacific Ocean.

1. Mariana Trench

Mariana Trench is the world’s deepest ocean trench, the deepest portion detected at 11.03 kilometers below the ocean’s surface, is located in the western Pacific Ocean, having a length of 2,550 km and a width of 69 km. The earth’s Poles distance is closer to the center of the earth, is 25 kilometers less in the poles than at the equator. The Mariana trench is not the closest point to the Earth’s center; the Arctic ocean bottom is around 13 kilometers closer to the center of the Earth.

It’s located about 200 km (124 miles) east of the Mariana Islands in the western Pacific Ocean. The first was the manned descent in submersible named Trieste ( a Swiss-designed, Italian-built deep-diving research bathyscaphe), owned by the US Navy, which reached at the bottom at 1:06 p.m. on January 23, 1960, with Don Walsh (USA) and Jacques Piccard (Switzerland) on board.
