The andesitic-dacitic Nevado de Chachani volcanic complex, located immediately north of Arequipa, consists of a 320 sq km group of Pleistocene lava domes, a stratovolcano complex, and a flank shield volcano. The central, 6057-m-high Nevado Chachani complex contains multiple vents along an arcuate line, including a well-defined summit crater at the western end. Two early Pleistocene ignimbrites were erupted from now-buried vents of older edifices. Thin lava flows from Chachani volcano overlie glacial moraines. Pleistocene lava domes form the northern end of the complex. The 8-km-wide, late Pleistocene to possibly Holocene lava shield of Pampa de Palacio on the SW side produced a well-preserved lava flow field that represents the youngest products of the Nevado Chachani complex.

The Global Volcanism Program is not aware of any Holocene eruptions from Nevado Chachani. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Nevado Chachani page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

The Nevado de Chachani volcanic complex, seen here from the SW near the village of Yura, consists of a 360 sq km group of Pleistocene lava domes, a stratovolcano, and a shield volcano. The central, 6057-m-high Nevado Chachani complex contains multiple vents along an arcuate line, including a well-defined summit crater at the western end. Cerro La Horqueta (left horizon) may represent the latest activity from Nevado Chachani, after which activity migrated to the 8-km-wide Holocene lava shield of Pampa de Palacio on the south side.

Nevado Chachani volcano towers north of the international airport at Arequipa, PerĂº. 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.

The glacier-capped Nevado de Chachani volcanic complex lies immediately north of the city of Arequipa. The central part of the 6057-m-high complex contains multiple vents along an arcuate line. Pleistocene lava domes form the glacier-covered northern end of the complex in this NASA image. A prominent lava-flow complex at the bottom-center part of the image with fresh-looking flow levees was erupted from the 8-km-wide lava shield of Pampa de Palacio of late-Pleistocene to possibly Holocene age.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
