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).

The Global Volcanism Program is not aware of any Holocene eruptions from Wallis Islands. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Wallis Islands page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

A dramatic barrier reef surrounds the Wallis Islands in this Space Shuttle view (with north to the left). Small explosion craters are visible on 7 x 14 km Uvea Island. Uvea and other low, forested islands are formed of flat-lying basaltic lava flows that are cut by explosion craters and capped by tuff cones and cinder cones. The island rises only 143 m above sea level. The numerous small shields (lava cones) and tuff cones were considered on morphological grounds to have been formed during the Pleistocene and Holocene.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. 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.
