Nevados de Chillán is a group of stratovolcanoes located in the Andes of the Bío-Bío Region, Chile, and is one of the most active volcanoes in the region. It consists of three overlapping peaks, 3,212 m (10,538 ft) Cerro Blanco (Volcán Nevado) at the northwest and 3,089 m (10,135 ft) Volcán Viejo (Volcán Chillán) at the southeast, with Volcán Nuevo in the middle. Volcán Viejo was the main active vent during the 17th-19th centuries, and the new Volcán Nuevo lava dome complex formed between 1906 and 1945, eventually growing to exceed Viejo in height by the mid 1980s.
