There are no Holocene eruptions known for Wallis Islands. 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 Wallis Islands consist of one relatively large island, 7 x 14 km Uvea Island, and 22 smaller islands and islets that are surrounded by a barrier reef. The low, forested islands, formed of flat-lying basaltic lava flows that are cut by explosion craters and capped by tuff cones and cinder cones, reach a maximum height of only 143 m above sea level. Numerous small shields (lava cones) and tuff cones are considered on morphological grounds to be of Pleistocene to Recent age (Stearns, 1945). Potassium-Argon ages of dated samples range from 0.5 to 0.08 million years old, but rocks of Pleistocene or Holocene age are present (Price et al., 1991).
