There are no Holocene eruptions known for Robledo. 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 6-km-wide Robledo caldera in NW Argentina is located 80 km SW of the much larger and better known Cerro Galán caldera. The Holocene Cerro Blanco del Robledo lava dome is located on the southern rim of the Robledo caldera (de Silva and Francis, 1991). Extensive rhyolitic pumice-fall deposits surround the dome. Well-preserved pyroclastic-flow deposits erupted prior to extrusion of Cerro Blanco are exposed on the floor of the caldera and on its NW flanks. Satellite geodetic surveys in the central Andes (Pritchard and Simons, 2002) showed subsidence of Robledo caldera in the 1990s.
