The INGEOMINAS volcanological observatory at Pasto has images from overflights carried out on 15 February 2010 over the volcanoes of southern Colombia: Galeras, Cumbal, Azufral and the Chiles-Cerro Negro complex (click on the name to access the images for each volcano).
Of these four, only Galeras is currently showing any signs of restlessness and is on alert level III, yellow (‘changes in the behaviour of the volcanic activity’). Cumbal and Azufral are both at alert level IV, green (‘volcano active and behaviour stable’), while Cerro Negro isn’t considered to need an alert level. Cumbal’s most recent eruptive activity was an explosive eruption in 1926, Azufral’s last known eruption was 1000 years ago, while Cerro Negro may have erupted in 1936, although this is unconfirmed.
