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.

The conical, glacier-clad Nevado de Longaví volcano is a late-Pleistocene to Holocene, dominantly andesitic stratovolcano constructed over a basement of Tertiary volcaniclastic and granitic rocks. Two edifice-collapse events modified the eastern and SW flank of a pre-Holocene volcano, and Holocene activity has been concentrated at the summit region and on the eastern flanks of the volcano. Andesitic-to-dacitic lava domes occupy the summit region, and a Holocene dome forms the 3242-m-high summit of Longaví. The last eruptions produced a lava dome in the upper part of the collapse scarp and summit region that partially collapsed to the east, forming block-and-ash flow deposits. No historical eruptions are known, although fumarolic activity continues.
