Manaro Voui, or Manaro Vui, is a shield volcano whose emergent portion is known as the island of Ambae in Vanuatu. The summit is 1,496 metres (4,908 ft) above sea level and about 3,900 m (12,800 ft) above the sea floor. According to indigenous custom Chief Virenaliu Paul Vuhu, the summit's valley and lakes are considered the "sacred place and paradise" where they believe after death, their spirits go to live happily ever after'. The Vanuatu Meteorology and Geohazards Department maintains a live webcam and seismological chart.

Volcanologists use the term 'volcano' to refer to either a "vent in the surface of the Earth through which magma and associated gases and ash erupt", or "the form or structure (usually conical) that is produced by the ejected material."

Aoba is the name of the volcano used by Volcano World in their world database in their list of Vanuatu's 9 volcanoes. Manaro is the name they use to refer to the summit crater, which contains multiple vents and lakes.

Aoba is also the name used by Smithsonian Institution's Global Volcanism Program in their list of 14 volcanoes on Vanuatu. Manaro Ngoru and Lake Voui are the names they use for the summit craters. In a 2005 report, The Bulletin of the Global Volcanism Network stated that Aoba is "referred to locally as Manaro or Lombenben"

Aoba is also the name used in The World Factbook written by United States Central Intelligence Agency.

Aoba is also the name used in a 2017 peer reviewed article in the journal Science, whose lead author works at NASA, and holds a joint appointment at the University of California, Los Angeles.

Lombenben is the name used on a 2017 map published by Vanuatu's National Disaster Management Office.

Lombenben is also the name used by the daily newspaper Vanuatu Daily Post in recent articles.
