Manuk Volcano — Indonesia

The small steep-sided island of Manuk is the easternmost volcano in the Banda volcanic arc. The truncated andesitic cone rises 3,000 m from the sea floor. No confirmed observed eruptions are known from this uninhabited island, although there was an uncertain report that a member of the 1874 Challenger Expedition saw "smoke" rising from the crater. Highly altered fumarolic areas are located within the crater and on its western rim, and were once the source of sulfur extraction by Chinese traders.
