Llaima's 2008 eruption as viewed from Temuco

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 also contributed to the project.
