Chiles-Cerro Negro

Chiles-Cerro Negro is an active stratovolcano at the Colombia-Ecuador border comprising two main peaks within the Andes mountain range. The two summits together form a single interconnected volcanic system.

The Chiles peak experienced its last major eruption approximately 160,000 years ago, while an unconfirmed volcanic event was reported in 1936. This represents an exceptionally long period of relative dormancy.

Local communities in the area use the hot springs and thermal waters fed by the volcanic system as part of their daily routines and practices. These natural features are woven into the way people live and interact with the landscape.

The area is known for seismic activity and is regularly monitored through observation stations. Visitors should be aware of potential earthquake activity and follow local safety guidelines.

Beneath the surface lie three major hydrothermal chambers that maintain constant geological activity despite minimal surface eruptions. These hidden structures make the system a fascinating example of underground volcanic dynamics.
