The Role of the Public Works Department in Mitigating Tsunami Impact: A Case Study of Kanyakumari District

Abstract

The 2004 Indian Ocean tsunami had a catastrophic impact on the coastal regions of Kanyakumari District, resulting in widespread devastation to human life, infrastructure, and the local economy. This study examines the tsunami’s effects on physical geography, including inundation distance, run-up elevation, and tsunami wave height, as well as its destructive influence on human settlements, fisheries, agriculture, and public infrastructure. Low-lying coastal areas experienced extensive inundation and sediment deposition, leading to the displacement of thousands and severe loss of livelihood resources. The lack of public awareness and preparedness significantly contributed to the human toll, particularly among children. The paper highlights the critical need for integrated coastal zone management, community-based disaster preparedness, and infrastructure resilience to mitigate the impacts of future tsunamis and related coastal hazards in the region.
