BackgroundOval-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).
