There are no Holocene eruptions known for Unnamed. 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.

A group of small islands south of Tongoa Island were considered to be remnants of a once-larger landmass that foundered during the Holocene. Ewose, Buninga, and Tongariki islands, at the southern end of the Shepherd Islands, lie on the rim of a proposed caldera thought to be one of several formed in the central volcanic chain of Vanuatu about 2000 years ago (Crawford et al. 1988, Macfarlane et al. 1988). Eissen et al. (1991) did not find evidence for a caldera at this location. Pyroclastic rocks intruded by dikes are exposed on Ewose, whereas Buninga and Makura are largely composed of tilted lava flows. Tongariki consists of remnants of a basaltic stratovolcano with dacitic pumiceous tuffs in low-lying areas.
