Purace (Colombia) - Report for 16 September-22 September 2026 - Continuing Eruptive Activity — volcanic activity reported was recorded by Global Incident Tracker on Thursday, 24 September 2026 at 11:03 UTC. The event is classified as a volcanic eruption incident with a severity rating of Moderate, and was detected through GVP.
The Servicio Geologico Colombiano (SGC) reported intensifying eruptive activity at Puracé during 16-23 September. Signals associated with fluid movement, mainly long-period (LP) events, dominated the seismicity and were located beneath Puracé volcano at depths less than 1 km. Seismic activity associated with rock fracturing (volcano-tectonic earthquakes) continued to be recorded, but a majority of signals were located in an area 13-18 km NE of Puracé at depths of 6-12 km. Sulfur dioxide flux gradually decreased, though it remained above average baseline levels, and soil carbon dioxide concentrations rose throughout the reporting period. Slow ground deformation persisted in an area between the Puracé, Piocollo, and Curiquinga volcanoes. Low-energy thermal anomalies were detected some days on the crater floor. On most days a few ash emissions were detected by the seismic network and/or obs
Where this happened
The incident is located in Colombia (South America), whose capital is Bogotá. Historically, Colombia is most affected by floods, landslides, earthquakes and volcanic activity. You can follow every incident recorded in this country, updated live, on the Colombia incident tracker.
Approximate coordinates of the reported event are 4.600°, -74.300°. The marker on the map above shows this position; for news-derived reports the location reflects the place named in media coverage and may represent a district or city rather than an exact site.
Understanding volcanic eruption events
Eruptions producing ash, lava, pyroclastic flows and lahars. Volcanic risk extends far beyond lava. Pyroclastic flows, ashfall that collapses roofs, lahars (volcanic mudflows) and aviation-grade ash clouds account for most volcanic casualties and economic damage.
How severity is rated
Global Incident Tracker rates every event on a four-step scale — Minor, Moderate, Severe and Extreme — derived from the source signal: earthquake magnitude, official GDACS alert colour, or the volume of independent media reporting for news-derived incidents. This event is currently rated Moderate. Ratings can change as more information becomes available, and a rating is a monitoring signal rather than an official government assessment.
Safety guidance for volcanic eruption situations
- Follow exclusion zones exactly — pyroclastic flows travel faster than any vehicle on local roads.
- Protect against ashfall with an N95 mask and eye protection; ash damages lungs and engines.
- Avoid river valleys and low ground downstream, where lahars concentrate.
- Clear roof ash carefully; wet ash is extremely heavy and collapses structures.
- Follow only official instructions from local authorities and emergency services — this page is a monitoring record, not an emergency alert.
Data and verification
This record was generated automatically from GVP and de-duplicated against our archive. Early reports for any incident can be revised: locations get refined, magnitudes are recalculated and impact figures change as assessments arrive. We deliberately do not publish casualty numbers unless an official source states them. The original source report is linked at the top of this page.
