"The majority of Fiji´s islands formed through volcanic activity starting around 150 million years ago. Some geothermal activity still occurs today, on the islands of Vanua ...
Levu and Taveuni.[18] The geothermal systems on Viti Levu are non-volcanic in origin, with low-temperature (c. 35–60 degrees Celsius) surface discharges. Sabeto Hot Springs near Nadi is a good example.[19] Humans have lived in Fiji since the second millennium BC—first Austronesians and later Melanesians, with some Polynesian influences. Europeans visited Fiji from the 17th century onwards,[20] and, after a brief period as an independent kingdom, the British established the Colony of Fiji in 1874. Fiji operated as a Crown colony until 1970, when it gained independence as the Dominion of Fiji. A military government declared a Republic in 1987 following a series of coups d´état. In a coup in 2006, Commodore Frank Bainimarama seized power. When the High Court ruled the military leadership unlawful in 2009, President Ratu Josefa Iloilo, whom the military had retained as the nominal Head of State, formally abrogated the 1997 Constitution and re-appointed Bainimarama as interim Prime Minister. Later in 2009, Ratu Epeli Nailatikau succeeded Iloilo as President.[21] After years of delays, a democratic election took place on 17 September 2014. Bainimarama´s FijiFirst party won 59.2% of the vote, and international observers deemed the election credible.[22]" - (en.wikipedia.org 19.10.2019)
