Cordón del Azufre, Volcanic complex in Central Andes, Chile
Cordón del Azufre is a volcanic complex in the Central Andes with multiple craters arranged along a ridge formation. The structure shows how successive volcanic eruptions built up the mountain over geological time, creating distinct peaks and crater openings across its slopes.
The volcano formed through tectonic processes where the Nazca Plate subducts beneath the South American Plate in this region. This ongoing plate convergence created the volcanic activity over millions of years that shaped the complex into its current form.
The surrounding volcanic terrain influences local populations who adapt their agricultural practices to the mineral-rich soils of the region.
Visitors need high-altitude mountaineering gear and experience navigating exposed terrain, as the landscape is steep and demanding. The elevation and harsh climate require good physical preparation and time to acclimatize before attempting the ascent.
The volcanic complex generates a ground inflation rate of 2.5 centimeters annually, indicating potential growth of an underground magma chamber.
