Run-up and inundation limits along southeast coast of India during the 26 December 2004 Indian Ocean tsunami

Abstract

The recent Indian Ocean Tsunami had a devastating effect on the Indian coastline. Apart from the Andaman and Nicobar Islands, the Tamil Nadu coast was the most affected. Post-Tsunami survey was carried out during January-February 2005 along the Tami Nadu coast to study the inundation limits and to estimate the run-up heights. This manuscript presents the results of the survey undertaken to estimate the inundation limits and the run-up heights, along the Tamil Nadu coast from Vedaranyam to Chennai. The results showed that average inundation was 238m inshore and average run-up height was 4.17m above Chart Datum north of Pondicherry.
