The largest island is
Gaua (formerly called Santa Maria), which has a rugged terrain, rising to
Mount Gharat, an active volcano at the centre of the island, at . Gaua's freshwater
Lake Letas, in its volcanic crater, is the largest lake in Vanuatu. A slightly smaller island in the group,
Vanua Lava, is higher, at ; it too has an active volcano:
Mount Suretamate (also spelled Süretimiat or Sere'ama, ). To the east of Vanua Lava are two islets in the groupo,
Ravenga and
Kwakea (also spelled Qakea).
Sola, the provincial capital, is on Vanua Lava. The third largest island in the group,
Ureparapara (also known as Parapara), is an old volcanic cone that has been breached by the sea, forming a bay, known as Divers Bay, on its east coast. To the east of these larger islands lie a number of smaller ones. The furthest north of them, northeast of Ureparapara, is
Vet Tagde (also known as Vot Tande or Vat Ganai), which is an extinct
volcano that last erupted 3.5 million years ago. Other small islands in this eastern chain in the Banks Island group include the
Rowa Islands (also called the Reef Islands), which are a few very small, low islands on a coral
atoll.
Mota Lava is the largest and highest (411 m) of this eastern chain of islands; off its southern coast, attached by high corals that can be waded through at low tide, is the tiny islet of
Ra. The islands of
Mota,
Merig, and
Merelava complete the southeastern part of the archipelago.
Islands Economy The principal economic activity is
subsistence agriculture, although
copra,
coffee and (on Gaua)
cacao are grown for export. The sulphur deposits of Mount Suretamate on Vanua Lava were formerly worked by a French company. Tourism is increasingly important on the islands, which can be reached by airplane.
Transport There are airports on Mota Lava, Vanua Lava and Gaua, served by
Air Vanuatu, which operates a few flights each week and Air Taxi Vanuatu as requested. Ships come to these islands, principally to pick up the products being exported, but they will also take passengers. ==History==
