A 90 m high island was formed in 1835, but then dwindled to only a few rocks in 1848. Another new island was formed in 1919 but then disappeared by 1935 .
Mount Banua Wuhu is in the southwest of Mahengetang Island which has an area of approximately 1 km2, the population living on the island is not necessarily, but only the fishermen and the manager of the coconut plantation.
