Ontong Java Atoll or Luangiua is one of the largest atolls on earth. It is sometimes referred to as Lord Howe Atoll, not to be confused with Lord Howe Island.
Geographically it belongs to a scattered group of three atolls which includes nearby Nukumanu Atoll and the wholly submerged Roncador Reef located 75 kilometres to the south.
