The Andaman Sea if sea level dropped
The slider on the map lowers the sea in steps. This table shows how much of the Andaman Sea's water would be land at each step.

|---|---|---|
| 10 m | 14,482 km² | 2.4% |
| 20 m | 30,032 km² | 4.9% |
| 50 m | 88,702 km² | 14.5% |
| 80 m | 143,388 km² | 23.4% |
| 120 m | 182,180 km² | 29.8% |
| 200 m | 204,421 km² | 33.4% |
| 500 m | 272,738 km² | 44.6% |

Frequently asked questions
How deep is the Andaman Sea?
On average about 1,071 m in the GEBCO grid (the middle value is 717 m). The deepest cell inside its outline is 4,524 m, at 10.02° N, 93.78° E.
How big is the Andaman Sea?
About 611,501 km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.
How much of the Andaman Sea would be land if sea level dropped?
With the sea 10 m lower, about 14,482 km² (2.4%) 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.
