Some historical maps indicate that an vulcano eruption on Gilibanta Island has significantly reshaped the island after 1835.

The small island of Gilibanta was reported by a pilot to be destroyed by a volcanic eruption in 1957, but the report has not been confirmed by scientific sources and is considered doubtful (Hantke, 1962). Ratman and Yasin (1978) map the island as a Quaternary volcano with a caldera open to the north forming Ouingke Bay.
All maps since 1943 show esentially the same concave shape of the island.
Here you’ll be diving inside a partially submerged volcano. There aren’t many places in the world where you can dive a volcanic cinder cone. Don’t worry; it is unlikely you’ll see any fireworks from eruptions because Gili Banta has been dormant since her last submarine eruption in 1957. But the nutrient rich substrate continues to feed a plethora of marine life that thrives in this type of environment.
The islands in Komodo National Park are volcanic in origin. The area is at the juncture of two continental plates: Sahul and Sunda. The friction of these two plates has led to large volcanic eruptions and caused the up-thrusting of coral reefs. Although there are no active volcanoes in the park, tremors from Gili Banta (last eruption 1957) and Gunung Sangeang Api (last eruption 1996) are common.
