摘要

The southern part of erstwhile Dhanushkodi township, Tamil Nadu, experienced subsidence and submergence during AD 1948-49. Shallow bathymetric and side-scan surveys together with sampling and underwater videography confirm the extent and quantum of subsidence. The studies reveal that a vertical tectonic movement (fault) parallel to the coastline with a displacement of - 5 m led to the subsidence of the southern part of the township. This fault movement has occurred 57 years ago and hence could be thelatest neo-tectonic movement ever recorded along the east coast of India.
