Geological Summary

Oval-shaped, 17-km-wide Aneityum Island, also known as Anatom or Anetchom, lies SE of Tanna Island and is the southernmost of the Vanuatu Islands chain. Aneityum consists of two coalescing, dominantly basaltic Pleistocene volcanoes. Both the NW side of Inrerow Atamwan volcano and the SE side of Nanawarez volcano are truncated by large erosional cirques. Volcanic activity ceased during the uppermost late-Pleistocene to Holocene (Carney and Macfarlane, 1979).

The Global Volcanism Program is not aware of any Holocene eruptions from Aneityum. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Aneityum 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.

Aneityum, also known as Anatom, consists of two coalescing, dominantly basaltic Pleistocene volcanoes. Both the NW side of Inrerow Atamwan volcano (left) and the SE side of Nanawarez volcano (right) are truncated by large erosional cirques. Volcanic activity ceased during the uppermost late-Pleistocene to Holocene. Fringing reefs are visible on the northern side of the island.

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.
