Earth Sandwich / City antipodes / Jabalpur

Antipode finder · India

The antipode of
Jabalpur.

Draw a straight line from Jabalpur (23.17° N, 79.95° E) through the centre of the Earth and it comes out at 23.17° S, 100.05° W, in the South Pacific Ocean, 650 km from the nearest dry land, off the coast of Chile. The other slice of an Earth sandwich would sink.

Two globes: one centred on Jabalpur, one centred on its antipode at 23.17° S, 100.05° W

Can you make an Earth sandwich from Jabalpur?

No, not from Jabalpur itself. The other slice would land in the South Pacific Ocean, 650 km from the nearest dry land (Chile), where the sea floor lies about 3,960 m below the surface. Boats do not count (Sandwich Law § 1.3).

The nearest place from which an exact Earth sandwich is possible is 1,022 km from Jabalpur, 25 km from Jaisalmer, India. Its other slice would go down 20 km from Hanga Roa, Chile.

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.
