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 (4 ft 11 in to 5 ft 9 in), 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.
