Authorities in Cauca, Colombia, are preparing emergency shelters following an increase in seismic activity at the Puracé volcano [1].
The escalation in volcanic activity poses a direct threat to local communities and agriculture, necessitating a rapid coordination of evacuation protocols and monitoring of gas emissions.
Reports regarding the current alert level for the volcano are contradictory. One report indicates the alert has been upgraded to orange [1], while another states the alert remains yellow [2]. Both sources agree that seismic events have increased, with the Servicio Geológico Colombiano (SGC) noting a rise in tremors from Wednesday to Friday associated with the movement of fluids [2].
The SGC identified several triggers for the heightened state of caution. These include an increase in seismic energy and higher temperatures in ash and gas emissions, specifically sulfur dioxide (SO₂) and carbon dioxide (CO₂) [1, 2]. The volatility of the volcano has already resulted in ash fallout affecting local crops [1, 2].
Local authorities in the Cauca department are currently organizing shelters to ensure residents have a designated place of safety should a full evacuation become necessary [1]. The preparation of these sites is a precautionary measure to mitigate the risk of casualties if the volcano enters a more active eruptive phase.
"According to the Colombian Geological Service, from Wednesday to Friday there has been an increase in earthquakes, associated with the movement of fluids," the SGC said [2].
“Authorities in Cauca, Colombia, are preparing emergency shelters following an increase in seismic activity at the Puracé volcano.”
The discrepancy between 'yellow' and 'orange' alert levels suggests a rapidly evolving situation or a lag in official communication channels. Regardless of the specific color code, the preparation of shelters and the observation of increased SO₂ and CO₂ emissions indicate that the SGC is treating the current seismic surge as a significant precursor to potential eruption, prioritizing human safety and crop protection in the Cauca region.
