There are no Holocene eruptions known for Calabozos. 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 26 x 14 km composite late-Pleistocene Calabozos caldera produced major rhyodacitic-to-dacitic ashflow sheets of ~200-500 cu km magma each, collectively referred to as the Loma Seca Tuff, at 0.8, 0.3, and 0.15 million years ago. Eruptive activity has continued into the Holocene, forming the 20-25 cu km dacitic-to-andesitic Cerro del Medio complex at the southern end of the caldera and the four clustered vents of Descabezado Chico near the western caldera rim. The late-Holocene 2.5 cu km Escorias dacitic lava flow from Descabezado Chico traveled >30 km to the south. Several hot-spring clusters are present along the margin of the central resurgent uplift within the caldera.
