Nevado del Ruiz, one of Colombia’s most formidable stratovolcanoes, looms over the region with a history of devastating eruptions and a current status that suggests an imminent threat. This volcano, part of the Andean volcanic belt, is notorious for its explosive power, which was most tragically demonstrated in the 1985 eruption. That event unleashed deadly lahars that buried the town of Armero, claiming the lives of over 23,000 people. Today, Nevado del Ruiz shows signs of reawakening, with increased seismic activity and elevated gas emissions detected by monitoring systems.

These indicators are alarming, as they often precede significant volcanic eruptions. The tremors suggest that magma is moving within the volcano, and the rising levels of sulfur dioxide and other volcanic gases point to escalating subterranean activity. This scenario has put both scientists and local communities on high alert, as the potential for another major eruption could spell disaster for the densely populated areas surrounding the volcano.
The dangers associated with a potential eruption of Nevado del Ruiz are manifold and severe. Pyroclastic flows, which are fast-moving currents of hot gas and volcanic matter, could devastate nearby communities with little warning. These flows are capable of destroying nearly everything in their path, leaving a trail of destruction. Additionally, ashfall from an eruption could blanket wide areas, leading to respiratory health issues, contamination of water supplies, and significant agricultural damage. The most dreaded threat remains the lahars, which are volcanic mudflows triggered by the melting of the volcano’s snow and ice cap.
These lahars can travel at high speeds down river valleys, engulfing towns and infrastructure in their way, as tragically witnessed in 1985. Given the potential for such catastrophic outcomes, there is an urgent need for robust disaster preparedness and effective communication systems to ensure the safety of those living in the vicinity of Nevado del Ruiz. Continuous monitoring and real-time data analysis by the Colombian Geological Service (SGC) are crucial in providing early warnings and facilitating timely evacuations. Community drills, public awareness campaigns, and international cooperation enhance these efforts, aiming to mitigate the risks posed by this powerful volcano.
