Trinket has an area of 12.25 km², and a flat, low topography. Regional monsoons bring rains of 3,000 mm to 3,800 mm yearly. The island is surrounded by shallow waters and coral reefs, which allow it to be approached by boat only during high tide.
Two early censuses of the island were conducted by the British administration in 1883 and 1901. The 1883 census revealed a population of 85 persons living in eight villages. The 1901 census indicated an estimated population of 102 persons, spread between four and six villages, ruled by two chiefs. As of 2001, the Indian census had catalogued 436 persons living on Trinket in four villages: Trinket, Safebalu, Tapiang and Hockcook. Like most other islands in the Nicobar district, Trinket's population was almost exclusively ethnic Nicobarese. Although, the 2011 Census of India indicated that the island had become uninhabited following the 2004 tsunami disaster, as of the end of 2012 the island appeared to have been repopulated by a pair of returnees, living at the site of what had been Trinket village.
Economy
From the fifteenth to the nineteenth centuries, trade with Trinket, as with the rest of the Nicobar Islands, was dominated by Indian, Arab, and European merchant fleets. Prior to the 2004 Indian Ocean earthquake, the island's populace was dependent on the outside world for many goods, including foodstuffs. Until the 1950s they exported whole coconuts and other forest products, but after the 1950s local production shifted toward exports of processed coconut, in the form of copra. Those products were traded for imports such as rice, sugar, and clothes, which were used to supplement the localsubsistence economy based on hunting and gathering, fishing, pig and chicken rearing, and household gardens.
History
Trinket was officially made subject to the British Empire in 1869. The island became part of sovereign India following Indian independence in 1947.
Like the other Nicobar and Andaman Islands, Trinket was devastated by tsunamis generated by the 2004 Indian Ocean earthquake. The island, which has a low and flat topography, was severely affected by the powerful waves and by earthquake-caused subduction of 1.5m to 1.75 m, suffering a reduction of its surface area from 14.6 km² down to 12.25 km². Initial reports that the island had been split apart were later confirmed by satellite imagery and onsite surveys.
Human toll
On Trinket, the tsunami left 91 dead or disappeared and the total devastation of the island's communities and economy. Shortly after the disaster, the entire remaining population of the island was evacuated to neighboring islands, principally Nancowry, and Kamorta, where the Indian government built a resettlement village called Vikas Nagar.
Repopulation of the island
By the end of 2012, only two people, both returnees, were reported to be living permanently on the island.
