On November 7th, the Vulcanological and Seismological Observatory of Popayán reported the change of the volcano to Orange Level (II). The orange level implies: Possible eruption in matter of days or weeks, due to a major increase in seismic activity, a significant increase in movement of magma to the surface has led to constant emission of gas and ash.

Population in the high risk areas are in Páez- Belalcázar and Inzá municipalities in Cauca department and La Plata, Nátaga, Paicol and Tesalia municipalities in Huila department.
