Sea level in metres below today’s. A simple bathtub model: it lowers the sea everywhere by the same amount and does not simulate how the water would really drain.

  • Deeper than 6,000 m

  • 2,000 to 4,000 m
  • 1,000 to 2,000 m
  • 200 to 1,000 m
  • Shallower than 200 m (the continental shelf)

Land height

  • Land up to 500 m
  • 500 to 2,000 m
  • Above 2,000 m

How to read the map. Darker blue is deeper water. Tap anywhere to see how deep the sea is there, or how high the land is, and the nearest named undersea feature. Depths come from the GEBCO_2026 grid, which in most of the deep ocean is predicted from satellite measurements of the sea surface rather than surveyed by ship, and the map’s tiles are coarser than the grid, so narrow trenches read shallower on the map than their true depth. Not for navigation.

Kuril–Kamchatka Trench is an oceanic trench. In the GEBCO grid it reaches 9,595 m below sea level. That figure is the deepest cell in the grid within 400 km of the centre point Wikidata gives for it (a trench is very long, and Wikidata lists a single point). The nearest country in our list is Russia, about 173 km from its listed point.

How deep is the Kuril–Kamchatka Trench?

The grid figure is 9,595 m. We measured it as the deepest cell in the grid within 400 km of the centre point Wikidata gives for it (a trench is very long, and Wikidata lists a single point). The cell is at 45.26° N, 152.79° E. The GEBCO_2026 grid has a value every 15 arc-seconds, about 460 m at the equator, so a very narrow feature can be a little deeper or shallower in reality than any grid cell shows.

Wikidata gives 10,542 m, which is 947 m deeper than the grid figure of 9,595 m. Published depths for the same feature often differ like this: they can come from one ship's sounding of one spot rather than a gridded model, or refer to a different part of a long feature. We show both, and use the grid figure in our headline numbers because every depth on this site then comes from one source.

Among the 39 trenches in our list it ranks 7th by depth. The list is the named features on Wikidata with a position at sea, so it is not every oceanic trench in the world.

About trenches

Oceanic trenches are long, narrow valleys where one tectonic plate slides beneath another. They hold the deepest water on Earth, and most lie around the edge of the Pacific Ocean.

This site lists 39 trenches, 31 of them with their own indexed page. See all undersea features.

Nearby undersea features

Distances are between listed points. A long feature such as a trench or ridge has a single listed point on Wikidata.
