The Taiwan Strait if sea level dropped
The slider on the map lowers the sea in steps. This table shows how much of the Taiwan Strait's water would be land at each step.
| Sea level lowered by | Becomes land | Share of its water |
|---|---|---|
| 10 m | 3,077 km² | 6.5% |
| 20 m | 6,470 km² | 13.7% |
| 50 m | 23,503 km² | 49.8% |
| 80 m | 45,352 km² | 96.1% |
| 120 m | 46,693 km² | 98.9% |
| 200 m | 47,201 km² | 100% |
| 500 m | 47,201 km² | 100% |
| 1,000 m | 47,201 km² | 100% |
| 2,000 m | 47,201 km² | 100% |
| 3,000 m | 47,201 km² | 100% |
| 4,000 m | 47,201 km² | 100% |
| 6,000 m | 47,201 km² | 100% |
A simple bathtub model: it lowers the sea everywhere by the same amount and does not simulate how water would really drain.

Frequently asked questions
How deep is the Taiwan Strait?
On average about 47 m in the GEBCO grid (the middle value is 50 m). The deepest cell inside its outline is 185 m, at 23.14° N, 119.80° E.
How big is the Taiwan Strait?
About 47,201 km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.
How much of the Taiwan Strait would be land if sea level dropped?
With the sea 10 m lower, about 3,077 km² (6.5%) 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.
