Gunung Api Lava Flows

Gunung Api is an active volcano rising from the Banda Sea, and its relatively recent lava flows have created a dramatic underwater landscape of black basalt ridges, rubble slopes, and overhangs that are rapidly being colonized by pioneering coral species. Pristine hard corals carpet the newer sections while older flows host dense gorgonian communities, and schooling surgeonfish and unicornfish graze the algae-encrusted lava in feeding frenzies. The site carries extra emotional weight — the island erupted in 1988 and the youngest underwater formations are coral pioneer communities on less than 40-year-old substrate.
