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.

How deep is each part of the Tyrrhenian Sea?

The bar splits the Tyrrhenian Sea's water by depth. Each colour is a depth band, and the shares add up to 100%.

  • 0 to 200 m: 14.3%
  • 200 to 1,000 m: 23.5%
  • 1,000 to 4,000 m: 62.3%
  • 4,000 to 6,000 m: 0%
  • below 6,000 m: 0%

Named features near the deepest point: Tyrrhenian Basin (6 km), Vercelli Seamount (169 km), Marsili (199 km), Palinuro Seamount (226 km).

Frequently asked questions

How deep is the Tyrrhenian Sea?

On average about 1,596 m in the GEBCO grid (the middle value is 1,445 m). The deepest cell inside its outline is 3,640 m, at 39.98° N, 12.26° E.

How big is the Tyrrhenian Sea?

About 215,504 km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.

How much of the Tyrrhenian Sea would be land if sea level dropped?

With the sea 20 m lower, about 3,067 km² (1.4%) of its water would be land. At 6,000 m lower, 100% would be. This is a simple bathtub model that lowers the sea evenly everywhere.

Data: depths from the GEBCO_2026 grid, statistics worked out inside the Natural Earth outline of the sea. See data sources and licences. The GEBCO Grid should NOT be used for navigation or for any other purpose involving safety at sea.
