Trinket Island (86 sq km) is part of the Nicobar Islands chain, located in the northeast Indian Ocean between the Bay of Bengal and the Andaman Sea. It is located east of Kamorta island and, like the Nicobar islands generally, is under the sovereignty of the nation of India. As of 2001, the Indian census catalogued 436 persons living on Trinket in four villages, Trinket (population 244), Safebalu (pop. 127), Tapiang (pop. 42) and Hockcook (pop. 23) ([1]).

Like the other Nicobar and Andaman islands, Trinket was devastated by tsunamis generated by the 2004 Indian Ocean Earthquake. The island, which had a low and flat topography, was split in two by the erosive power of the waves ([2]).
