Geological Summary

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.

MODVOLC - HIGP MODIS Thermal Alert System Using infrared satellite Moderate Resolution Imaging Spectroradiometer (MODIS) data, scientists at the Hawai'i Institute of Geophysics and Planetology, University of Hawai'i, developed an automated system called MODVOLC to map thermal hot-spots in near real time. For each MODIS image, the algorithm automatically scans each 1 km pixel within it to check for high-temperature hot-spots. When one is found the date, time, location, and intensity are recorded. MODIS looks at every square km of the Earth every 48 hours, once during the day and once during the night, and the presence of two MODIS sensors in space allows at least four hot-spot observations every two days. Each day updated global maps are compiled to display the locations of all hot spots detected in the previous 24 hours. There is a drop-down list with volcano names which allow users to 'zoom-in' and examine the distribution of hot-spots at a variety of spatial scales.
MIROVA Middle InfraRed Observation of Volcanic Activity (MIROVA) is a near real time volcanic hot-spot detection system based on the analysis of MODIS (Moderate Resolution Imaging Spectroradiometer) data. In particular, MIROVA uses the Middle InfraRed Radiation (MIR), measured over target volcanoes, in order to detect, locate and measure the heat radiation sourced from volcanic activity.
