Una-Una
Una-Una is an Indonesian island, part of the Togian Islands in the Gulf of Tomini.
Una-Una is a small volcanic island created by the Colo volcano. Its vegetation primarily consists of coconut trees. It forms the Una-Una District within the Tojo Una-Una Regency in the Central Sulawesi Province of Indonesia.
Most of the island was devastated by pyroclastic flows following an eruption of the volcano in 1983. It covers a land area of 146.16 km2 and had 8,395 inhabitants living in 11 villages in mid 2024.
Una-Una is surrounded by thriving reefs home to large schools of fish. It has been known as a location for scuba-diving since the 1990s.
