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.

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.

Terror Fracture Zone is a fracture zone. In the GEBCO grid it reaches 2,141 m below sea level. That figure is the depth in the grid at its listed centre point, so a typical depth for the feature, not its deepest or shallowest point. The nearest country in our list is Antarctica, about 873 km from its listed point.

Open the main map at its listed point and tap anywhere to read the depth.

How deep is the Terror Fracture Zone?

The grid figure is 2,141 m. We measured it as the depth in the grid at its listed centre point, so a typical depth for the feature, not its deepest or shallowest point. 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 has no depth figure for this feature, so the grid is our only source for it.

Among the 29 fracture zones in our list it ranks 27th by depth. The list is the named features on Wikidata with a position at sea, so it is not every fracture zone in the world.

About fracture zones

A fracture zone is a long scar in the seabed, where blocks of ocean crust on either side of a ridge have slid past each other.

This site lists 29 fracture zones, 17 of them with their own indexed page. See all undersea features.

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