Mota Lava or Motalava (coordinates 13°42′S 167°39′E / 13.7°S 167.65°E / -13.7; 167.65) is the fourth largest island in the Banks Islands of Vanuatu, after Gaua, Vanua Lava and Ureparapara, with an area of 24 km² (9.3 sq mi). It is the largest and highest (411 m/1,348 ft) of the eastern chain of islands. 270 meters (886 ft) off its southern coast, attached by high corals that one can wade through at low tide, is the islet of Ra, with an area of 0.5 km² (0.19 sq mi).

The 2009 census figures^[1] give a population of 1640 inhabitants (Mota Lava + Ra), yielding a population density of 67 per km².

There is an airport on the island (IATA code: MTV).

Name and language

In early texts and maps of the 19th century, the island of Mota Lava was designated as Saddle Island, due to the island's distinctive profile seen from a boat.

The habit of designating the island as Mota Lava was then borrowed by 19th-century missionaries from the neighbouring language Mota. The inhabitants of Mota Lava call their own island Mwotlap (pronounced [ŋmʷɔtˈlap]).

Mwotlap also designates the language spoken by the inhabitants of Mota Lava. It is the most widely spoken of the languages in the Banks Islands, with about 2,100 speakers.

An earlier attempt to transcribe the native name, both for the island and the language, yielded a form Motlav.

Geology

Mota Lava is composed of at least five basaltic stratovolcanoes. Two of the cones, Vetman and Tuntog, are well-preserved. Vetman is a pyroclastic cone in the centre of the island with a breached summit crater. At the southwest end of the island, Tuntog is a composite cone with a 500 meters (1,640 feet) wide crater.

Geochemical analysis shows that the island's lava has a similar composition to that from nearby Mota and Ureparapara, as well as lava from the south of the country, but differs from material erupted in central Vanuatu. The latter region has been affected by the subduction of a submerged, extinct island arc complex called the D'Entrecasteaux Zone.
