Dhanushkodi is an abandoned town at the south-eastern tip of Pamban Island of the state of Tamil Nadu in India. It is situated to the South-East of Pamban and is about 18 miles west of Talaimannar in Sri Lanka. The town was destroyed during the 1964 Rameswaram cyclone and remains uninhabited in the aftermath.
The area around Rameswaram is prone to high-intensity . A scientific study conducted by the Geological Survey of India indicated that the southern part of Dhanushkodi facing the Gulf of Mannar sank by almost 5 metres (16 ft) in 1948 and 1949, due to vertical tectonic movement of land parallel to the coastline.
