There are no Holocene eruptions known for Nevado Chachani. If this volcano has had large eruptions prior to 10,000 years ago, information might be found in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).
The following references are the sources used for data regarding this volcano. References are linked directly to our volcano data file. 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. Additional discussion of data sources can be found under Volcano Data Criteria.

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.
