Puracé volcano in Colombia increases activity with ash emissions

The Puracé volcano in southwestern Colombia is exhibiting a "significant" increase in activity, according to the Colombian Geological Service (SGC). The volcano, located in the Cauca department, has shown rising seismicity associated with gas dynamics within its volcanic conduits. This surge in activity has prompted concerns, particularly as the region prepares for the presidential inauguration.

The SGC reported ash emissions reaching up to 2,100 meters in altitude over the past week, leading to the suspension of flights at the Popayán airport, the departmental capital. Thermal imaging cameras have registered gas temperatures as high or higher than those observed during a similar episode in 2025. The volcano and the surrounding Coconucos volcanic chain remain on a yellow alert, with the possibility of further increases in activity or new emissions.

This heightened volcanic activity coincides with the preparations for the inauguration of President-elect Abelardo de la Espriella, scheduled for August 7 in Cauca. The Senate has approved the ceremony's location in the department, though the Chamber of Representatives is yet to vote. If approved, the volcanic phenomenon could potentially affect the logistics for guests attending the ceremony.

The Puracé volcano, one of 15 cones in the Coconucos chain, last had a significant eruption in March 1977. However, it has shown gradual changes in its activity since 2021. The SGC advises the public to avoid the upper parts of the volcanic chain, rely on official information channels, and follow the instructions of local authorities and the National Unit for Disaster Risk Management.
