The island of Vella Lavella is located in the southwestern Pacific Ocean. To the north is the island of Choiseul, to the northwest is the island of Shortland, and to the southeast is the island of New Georgia. Vella Lavella is a volcanic island, surrounded in some places by a coral reef. The island contains volcanic cones and one thermal spring. The highest elevation is Mount Tambisala at 790 metres (2,590 ft). The volcano Nonda (the youngest volcano of the island), has an elevation of 750 meters and is considered active, although it has never erupted in modern times. The smaller rivers running from the mountains to the coast allow irrigated horticulture to the inhabitants who live almost exclusively on the coast.
The climate on the island is wet, and tropical, and the island is prone to earthquakes and cyclones.
Painted potsherds found during excavations date back to an age of 2,000 to 3,000 years.
The Bilua language spoken on the island belongs to the Papuan languages, while the other languages of the Solomon Islands belong to the Austronesian languages. Therefore, archaeologists suspect the immigration of a people who did not come from the Melanesian settlement area.
On March 15, 1893 Vella Lavella was declared part of the British Solomon Islands protectorate. The island was occupied by the Empire of Japan in the early stages of the Pacific War. The Land Battle of Vella Lavella was fought between Allied and Japanese forces from 15 August - 6 October 1943. After a landing at Barakoma on 15 August, US troops advanced along the coasts, pushing the Japanese north. In September, New Zealand troops took over from the Americans and they continued to advance across the island, hemming the small Japanese garrison consisting of 250 Japanese personnel, who were a mix of soldiers evacuated from New Georgia and sailors who had been stranded on the island.along the north coast. On 6 October, the Japanese began an evacuation operation to withdraw the remaining troops, during which the Naval Battle of Vella Lavella was fought. Following the capture of the island, the Allies developed it into an important airbase which was used in the reduction of main Japanese base at Rabaul. Subsequently, Barakoma Airfield on Vella Lavella was the home base for VMF-214 (the "Black Sheep," led by Gregory Boyington).
Since 1978, the island has been part of the independent state of the Solomon Islands.
