Nevado Chachani volcano towers north of the international airport at Arequipa, Perú. The massive, 360 sq km volcanic complex includes a group of stratovolcanoes forming the horizon in this view, an older lava dome complex, and a younger SW-flank shield volcano. The dark hills in the left-center foreground are the distal margins of viscous lava flows from the Pampa de Placio, the SW-flank shield volcano. Volcanism has migrated to the west, and this marks the most recent activity of the Nevado Chachani complex.
