Aoba, also known as Ambae or Leper's Island, is an island in the South Pacific island nation of Vanuat. Ambae has a population of less than 10,000, divided into 3-4 discernible language groups (North/East Ambae language centered around the Lombaha area, West Ambae language centered around Nduindui, and South Ambae language centered around Redcliff). The island has no considerable towns, though the Penama provincial center is located at Saratamata on East Ambae, and there are three airstrips with service by Air Vanuatu, at Walaha (W), Redcliffe Airport(S), and Longana(E).
Rough, black basalt stones compose its shoreline and surface in many places, though the soils (where present) are rich. The island appears to be covered in nearly unbroken vegetation; inhabited areas feature large gardens and managed forests above, with coconut and cacao plantations usually closer to shore. There are no reliable sources of surface water (rivers, streams, or lakes), save the crater lakes which are inaccessible. Water for all human uses comes from cement-lined wells or water tanks filled with rainwater.
Manaro is widely regarded as one of the world's top ten 'most dangerous' volcanoes, in terms of potential for a catastrophic eruption. One theory has it that given a large eruption, the water in Manaro's crater lakes could become superheated steam and cause a massive phreatic explosion. The resulting landslides down the island's steep slopes could cause tsunamis within Vanuatu's northern archipelago.
