Galeras stratovolcano in southwestern Colombia near the city of Pasto, is one of sixteen Decade Volcanos. The list of volcanoes are those considered most dangerous due to “their history of large, destructive eruptions and proximity to populated areas”.

Cayambe, the third highest mountain in Ecuador, is a stratovolcano with a permanent snowcap.

Nevado Chachani, one of highest volcanoes in southern Peru, has archaeological remains near the summit.

The volcanic caldera Chaiten is located in southern Chile near the Gulf of Corcovado.

Chaiten, which had been inactive for 9,500 years, began erupting in May of 2008; almost all inhabitants of the town of Chaitén and nearby villages were evacuated. The seimic and volcanic activity caused lahars, or flows of mud and debris, that in turn caused flooding that destroyed Chaiten. The town is being rebuilt.

Chaiten eruptions produced a translucent grey obsidian (volcanic glass) which was used by pre-Columbian cultures for artifacts.

Cotopaxi, a stratovolcano in the Andes Mountains, is located just 28 km (17 mi) south of Quito, the capital of Equador.
