Orona atoll, also known as Hull Island, is one of the Phoenix Islands in the Republic of Kiribati. measures approximately 8.8 km by 4 km, and like Kanton, is a narrow ribbon of land surrounding a sizable lagoon with depths of 15–20 metres. Numerous passages connect the lagoon to the surrounding ocean, only a couple of which will admit even a small boat. Total land area is 3.9 km2, and the maximum elevation is nine metres.
Although occupied at various times during the past, including as late as 2004, Orona is uninhabited today.
