Sebuku (also spelled Seboekoe or Sebeekee) is an island in the Sunda Strait between Java and Sumatra. It is one of the larger islands in the strait and lies just 2.5 kilometres (1.6 mi) to the north of Sebesi and 2.3 kilometres (1.4 mi) south of Sumatra. It is administratively part of South Lampung Regency, Lampung.
At the time of the 1883 eruption of Krakatoa, Sebuku was uninhabited, but a village on Sebuku Ketjil, a small island to its east, was completely wiped out. Official records give 150 killed, with 70 being non-residents.
In the 1920s, copra palms were planted on Sebuku to satisfy the growing market. However, due to a lack of maintenance the palms eventually withered and died.
In 1999 a sunken Japanese ship was found near Sebuku by divers preparing for an underwater photography contest. Its age is unknown.
Sebuku is a low island, located in the eastern part of the mouth of Lampung Bay, 2.5 kilometres (1.6 mi) north of Sebesi and 2.3 kilometres (1.4 mi) south of Sumatra. It covers a total area of 17.71 square kilometres (6.84 sq mi). It is administratively part of South Lampung Regency, Lampung.
Sebuku has a centre composed of andesite, indicating an early volcanic history. This centre has been dated to the Quaternary and has been called an early manifestation of volcanism in the Sunda Strait. The substrate on the northern side of the island consists of fossilised coral, mud and sand, while on the eastern side of the island the substrate consists of mud, sand, gravel, and both live and fossilised coral. The outside is fringed by a reef.
Sebuku, along with Sebesi, has been noted as a "stepping stone" for butterfly migration between Sumatra and Krakatoa. There are numerous butterfly species from both Java and Sumatra on Sebuku. Four species of ants have been found on Sebuku, fewer than Sebesi and Krakatoa. These included ants not found on Krakatoa, thought to be descended from fauna that survived the 1883 eruption.
