The antipode of
Touba.
Draw a straight line from Touba (14.86° N, 15.88° W) through the centre of the Earth and it comes out at 14.86° S, 164.12° E, in the Coral Sea, 260 km from the nearest dry land, off the coast of Vanuatu. The other slice of an Earth sandwich would sink.

Can you make an Earth sandwich from Touba?
No, not from Touba itself. The other slice would land in the Coral Sea, 260 km from the nearest dry land (Vanuatu), where the sea floor lies about 4,040 m below the surface. Boats do not count (Sandwich Law § 1.3).
The nearest place from which an exact Earth sandwich is possible is 260 km from Touba, 67 km from Sémé, Senegal. Its other slice would go down 61 km from Port-Olry, Vanuatu.
Touba is on the The South Pacific ↔ the Sahara & Sahel corridor. Its guide lists where every city on both sides lands and how to make an Earth sandwich there.
How this was worked out: the antipode flips the latitude and moves the longitude by 180°. Land or sea comes from the OpenStreetMap coastline the map uses; the sandwich verdict and elevations come from the verifier's 0.2° grid (Natural Earth land, ETOPO 2022 relief); water names from Natural Earth; towns and populations from GeoNames. The city's position is GeoNames' point for it; a big city's suburbs spread tens of kilometres around that point, and the figures move with them. Generated 2026-09-29.
