Bilangbilangan is one of the string of islands located in the Danajon Bank, the only double barrier reef in the Philippines, which is known to be rich in marine resources.
There is another island off the coast in the town of Bien Unido in the eastern side of Bohol, which is similarly named Bilangbilangan.
The US Geological Survey has confirmed that since the earthquake, the islands in the Cebu Strait have flooded to a depth of up to 43 cm (17 in) at high tide.
Although the government has offered a relocation program, many locals don't want to leave, instead choosing to stay on the island since their way of life depends on fishing.
The island can also be directly reached by bangka docked in Pasil Fish Port in Cebu City.
