Regional Seismic and Tsunami Susceptibility Assessment of ChennaiNagapattinam Coast of Tamilnadu and Pondicherry
Journal Title: International journal of Emerging Trends in Science and Technology - Year 2017, Vol 4, Issue 8
Abstract
Coastal areas in general and Tamilnadu Coast in particular is experiencing rapid urbanization and put to variety of uses. The threat of natural disaster for the shore based activities is ever increasing and the susceptibility status of earthquake and Tsunami with respect to coastal tectonics for the ChennaiNagapattinam coast of Tamil Nadu and Pondicherry is analysed regionally in this study. The study revealed the requirement of on shore and offshore beach ridges mapping, dating and understanding its emergence in combination with paleo seismicity. Further it is emphasised that the historical and paleo tsunami deposits identification and using this data for the future prognosis is vital for managing the future Tsunami disasters. Based on the available geological and tectonic information it can be inferred that even though the offshore areas adjoining the Tamilnadu coast appears to be low to moderately susceptible for earthquake and tsunami generation, understanding the neotectonism and detailed research in the gap areas for the studied coastal sector have been highlighted in this study
