Which mountain is the highest volcano on Earth, rising about 6,893 meters in the Andes?

Ojos del Salado is the highest volcano on Earth, rising about 6,893 meters in the Andes.

The volcano lies on the border between Chile and Argentina in the high Andes. Its summit reaches approximately 6,893 meters above sea level, making it the second-highest mountain in the Western Hemisphere after Aconcagua and the highest active volcano on Earth. It is part of a region shaped by the subduction of the Nazca Plate beneath the South American Plate.

Ojos del Salado is classified as an active volcano, although its most recent known eruption is uncertain and evidence points to only minor historical activity. A small crater lake near the summit is often described as the world’s highest lake of its kind, though measurements and definitions can vary.

Kilimanjaro is Africa’s highest mountain and a famous high volcano, but it is lower than Ojos del Salado. Mount Elbrus is Europe’s highest peak under common geographic definitions. These comparisons explain why the volcano’s specific superlative is important.
