BackgroundNevado Chachani volcano forms a 320 sq km complex of lava domes, a central stratovolcano and a flank shield volcano, suggesting a migration of vents from N towards SW:
1) Cerro Nocarane and Cerro Penones are 2 lava domes on the north flank. These domes are older than the last ice age.
2) The Nevados de Chachani stratovolcano itself, probably still active.
3) The 8 km diameter lava shield Pampa de Palacio (Las Cortaderas) on the south flank. The most recent eruptions of the volcano occurred here, forming a thick lava field.
