Chiles Volcano
Carchi
Chiles Volcano, located on the border between Colombia and Ecuador, is part of the Chiles-Cerro Negro volcanic complex alongside Cerro Negro de Mayasquer. The volcano is composed primarily of andesitic rock and has not erupted for approximately 160,000 years. Despite its dormancy, the area has experienced significant seismic activity, including a major M 5.8 earthquake in October 2014, which triggered an alarmingly high number of earthquakes in a short period. The complex is also known for its hydrothermal systems, featuring two distinct groups of hot springs: the acidic Aguas Hediondas with one of the highest hydrogen sulfide concentrations measured worldwide, and the neutral pH Aguas Termales de Tufiño with commercial bathing pools. These unique geological and hydrothermal features make Chiles Volcano an intriguing natural site for scientific study and eco-tourism.

Tip: Visitors should plan their visit during the dry season for safer and more comfortable conditions. It is advisable to check local seismic activity updates before traveling, as the area is seismically active. Booking guided tours can enhance safety and enrich the experience, especially to visit the hydrothermal springs. Commercial bathing pools at Aguas Termales de Tufiño offer a relaxing option for visitors. Advance reservations may be required for access to certain facilities, and visitors should respect local regulations to preserve the natural environment.
Interesting facts
- •The Chiles-Cerro Negro volcanic complex experienced over 7,700 earthquakes in a single day in October 2014, the highest since seismic monitoring began in 2013.
- •Aguas Hediondas spring near Chiles Volcano contains exceptionally high hydrogen sulfide levels (154 mg/L), among the highest recorded in terrestrial hot springs worldwide.
- •The 2014 earthquake swarm caused a temporary change in water color in the hot springs, visible for several days before returning to normal.
- •Chiles Volcano has not erupted for approximately 160,000 years, making it a dormant volcano with ongoing seismic activity.
History
Chiles Volcano is part of a volcanic complex that has remained dormant for about 160,000 years.
The region has experienced intermittent seismic swarms, with notable activity recorded since 2013.
A significant earthquake of magnitude 5.8 occurred in October 2014, marking the largest seismic event in the area to date.
This event led to the highest number of earthquakes recorded in a single day since the local seismic network was established in 2013.
The volcano's hydrothermal systems have been studied for their unique chemical compositions, particularly the acidic Aguas Hediondas springs.
