Below is a summary of eruption dates and Volcanic Explosivity Indices (VEI).

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.

Cerro del Azufre is the largest and youngest volcanic center of a 50-km-long, NW-SE-trending chain of Chilean volcanoes just west of the Bolivian border, south of Salar de Ascotán. The northern summit forms the 5846 m high point of the andesitic volcano; an older southern stratovolcano extends SE towards the Pleistocene Cerro Aguilucho volcano. A large group of late-Pleistocene lava flows originating from the northern cone extend toward the northern flanks and partially overlies a debris-avalanche deposit now largely buried by the Salar de Ascotán. The Chanka (Pabellón) dacitic lava-dome complex occupying the lower western flank is pristine-looking, but has been Potassium-Argon dated at 1.5 million years. Two possible Holocene dacitic lava domes that were erupted along a NW-SE line east of the summit ridge mark the most recent effusive activity of the Cerro del Azufre complex, but two youthful-looking craters on the main edifice could be of Holocene age.
