Futuna Island
It was formed by the uplift of an underwater volcano, which last erupted in the Pleistocene, at least 11,000 years ago. It reaches a height of 666 m. It is sometimes called West Futuna to distinguish it from Futuna Island, Wallis and Futuna, and also can be known Erronan by its island neighbour, Tanna. Although it is part of the Melanesian country of Vanuatu it is considered to be a Polynesian outlier.
