This Acropora table coral was seriously damaged, but the colony is regrowing over the damaged table. The white edges are the growing zones. \nObviously this colony has a high recovery potential and over all the resilience of the reef is exceptional: \nWhen the Banda volcano last blew its top in 1988, a large lava flow swept down the northern slope into the ocean, covering a large part of reef in volcanic rock. What many thought would be the total destruction of the reef has instead become one of the most incredible coral reefs in Indonesia. Measured from ground zero after the eruption in 1988, this particular reef is known to be the fastest growing coral in the world. \nLava Flow, Banda Neira Island, Indonesia, \n4°30'20.418 S 129°52'57.456 E at 9m depth
