[^2]\n\nThe Colombian Geological Service (SGC) maintains an Orange Alert for Purace Volcano in the Cauca region due to high activity levels reported by residents and the service itself. [^3]\n\nInstrumental records from the last few weeks remain above the historical baseline lines established for Puracé. [^4]\n\nThe SGC stated that the volcano's activity continues to show important changes in different parameters monitored by surveillance teams. [^5]\n\nInstruments inside Purace Volcano registered primarily tremors associated with the movement of magmatic and hydrothermal fluids at depths of less than two kilometers. [^6]\n\nResidents and community sentinels confirmed the fall and accumulation of ash in the Cristales and Loma Linda neighborhoods, although weather conditions made it difficult to determine the column height. [^7]\n\nTwo new ash emissions occurred starting at 2:00 p.m. on Thursday and continued until the latest technical bulletin was issued. [^8]",
