BackgroundSierra Nevada is a late-Pleistocene glaciated stratovolcano with a 7-km-long E-W zone of fissure vents that lies about 15 km NE of Llaima volcano. The age of Sierra Nevada has been considered to be late-Pleistocene (Moreno and Naranjo, 1991) or late-Pleistocene to Holocene (González-Ferrán, 1995). Naranjo (pers. comm., 2004) noted that no eruptions have occurred during the Holocene. The volcano has erupted dominantly andesitic to basaltic lava flows and pyroclastic material and has produced pyroclastic flows and lahars.
