This reef was significantly destroyed 1988 during a volcanic eruption and the flow of lava over it. However, it has made quite a recovery, leaving scientists astonished; in a few years only the coral  mostly Acropora species  rapidly grew back and currently thrives, a unique happening since in other reef locations around the world, the coral does not grow back at all after the eruption of a volcano. \nThe coral reef of Gunung Api is pristine now, has vaste areas with no bleached or damaged corals (May 2023). Banda Island is in the coral triangle, the roughly triangular area of the tropical marine waters of Indonesia, Malaysia, Papua New Guinea, Philippines, Solomon Islands and Timor-Leste that contain at least 500 species of reef-building corals in each ecoregion. \nNear Banda Island, Indonesia, 4°30'41.556 S 129°53'19.056 E
