Following an earthquake on 21 October in the area of the Chiles Volcano in Cumbal (Nariño department) on the border between Colombia and Ecuador, the Colombian geological authorities have declared an orange alert in the surrounding area. 12,000 people in southern Nariño have been ordered to evacuate their homes because of a possible imminent eruption.
Monitor local media and seek information and advice from the local authorities before travelling on the Pan-American highway, which passes near the volcano. Call #767 for information (in Spanish) from the Colombian Highway Police about road closures.
