Chimborazo is an Ecuadorian stratovolcano.

Why Is It Famous?

Chimborazo is famous for being the tallest mountain in Ecuador at the height of 6,263.47 meters. Its summit is also highly unique because it is the farthest point on the surface to the center of the earth. This is due to the mountain’s location on the equatorial bulge. This also means that it is the closest spot on the planet to outer space.

What Is Nearby?

The mountain is in the Cordillera Occidental Range, which is part of the Andes. It is in Ecuador’s Chimborazo Province, about 150 kilometers to the south-southwest of Quito, the country’s capital. It is also near to Carihuairazo, which is 5,018 meters high. It is also part of the Avenida de Los Volcanes.

Geological Description

Geologists classify Chimborazo as an inactive stratovolcano. It sits on the Ecuadorian Volcanic Arc’s main end. The top of the mountain is fully covered with glaciers. Some of the northeastern glacier arms flow down as low as 4,600 meters. The glaciers on the peak provide water to nearby provinces. Locals also mine the glacial ice.

This inactive volcano features one volcanic edifice over another. There are four summits, with Whymper Peak being the highest, followed by Veintimilla, Politecnica, and finally, Nicolas Martinez. As a stratovolcano, Chimborazo has low slopes at its bottom that increase in steepness as you go up the volcano.

Experts agree that Chimborazo’s peak is the farthest point from the center of the earth without leaving the planet. This comes from the earth’s oblate spheroid shape and the thickness around the equator. Since Chimborazo is just one degree to the south of the equator, it gets to add this thickness. If you look at the elevation above sea level instead of distance from the earth’s center, Chimborazo is not the Andes’ highest peak.

Events in Time

The most recent eruption of Chimborazo that geologists know of took place approximately 550 A.D.


Chimborazo is a stratovolcano with a summit that stands out as the farthest point from the center of the earth thanks to the mountain’s location right by the equator.
