There are no Holocene eruptions known for Tuzgle. 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 easternmost young stratovolcano of the central Andes, Cerro Tuzgle is located in Argentina about 120 km E of the main volcanic arc. Many youthful-looking flank lava flows were erupted from the well-preserved summit crater. Schwab and Lippolt (1976) obtained a Potassium-Argon date of 0.1 million years ago on what they believed to be the youngest Tuzgle lava. However, de Silva and Francis (1991) and González-Ferrán (1995) considered the latest activity to be of Holocene age, and Coira and Kay (1993, Fig. 2B) placed the youngest flow at the Pleistocene-Holocene boundary. Activity began with the eruption of a rhyodacitic ignimbrite, followed by construction of a lava dome complex on the rim of an existing caldera. Andesitic lava flows covered much of the dome complex and later partially filled the crater. Several edifice-collapse events occurred during the evolution of the volcano. The youngest flows were erupted on the SE and SW flanks.
