21 January-27 January 2009

Based on a SIGMET and analysis of satellite imagery, the Buenos Aires VAAC reported that during 21-22 January ash plumes from Nevados de Chillán rose to altitudes of 3.7-6.1 km (12,000-20,000 ft) a.s.l. and drifted 50-80 km SE. The VAAC also reported that an ash plume from Callaqui, a nearby volcano 120 km S, drifted NE on 22 January.

The compound volcano of Nevados de Chillán is one of the most active of the Central Andes of Chile. Three late-Pleistocene to Holocene stratovolcanoes were constructed along a NNW-SSE line within three nested Pleistocene calderas, which produced ignimbrite sheets extending more than 100 km into the Central Depression of Chile. The largest stratovolcano, dominantly andesitic, 3212-m-high Cerro Blanco (Volcán Nevado), is located at the NW end of the group, and 3089-m-high Volcán Viejo (Volcán Chillán), which was the main active vent during the 17th-19th centuries, occupies the SE end. The new Volcán Nuevo lava-dome complex formed between 1906 and 1945 between the two volcanoes and grew to exceed Volcán Viejo in altitude. The Volcán Arrau dome complex was constructed SE of Volcán Nuevo between 1973 and 1986, eventually exceeding its height by 20 m.
