Southern Andean Volcano Observatory

Llaima's 2008 eruption as viewed from Temuco

The Southern Andean Volcano Observatory (Spanish: Observatorio Volcanológico de los Andes del Sur), also known by its acronyms as OVDAS, is a program of the Chilean National Geology and Mining Service to watch the most dangerous volcanoes of the Southern Volcanic Zone in Zona Sur and Palena. The headquarters are at Cerro Ñielol at Temuco from where there is good sight to Llaima and Villarrica, two of Chile's most active volcanoes. Much of the OVDAS work is made in collaboration with CONAF that administers the national parks and reserves where many volcanoes are located. The regional government of Araucanía Region is also contributing to the project.

This is a list of the volcanoes with activity reports made by the OVDAS.^[1]
