Research Scholar, Department of Harbour and Ocean Engineering, AMET University Plot No.135, East Coast Road, Kanathur, Chennai - 603112, Tamil Nadu, India *Corresponding Author: [email protected] Abstract: The 2004 Sumatra tsunami left a deep and dark footprint on coastal Cuddalore in south east India, which was one of the worst affected districts in the main land. Assessment of natural hazards typically relies on analysis of past occurrences of similar disaster events. Assessment of tsunami hazard to the Indian coast poses a scientific challenge because of the paucity of both historical events and data. However, construction of the tsunami hazard maps is the key step in tsunami risk assessment and forms the basis for evacuation and future land use planning along coastal areas. To this end, a set of inundation scenarios were built based on realistic tectonic sources that can generate tsunamis in the Indian Ocean. From the past historical records three earthquake sources have been identified and a hypothetical worst case scenario was also generated.

Previously, the State Planning Commission has published Human Development Report for 8 districts in the past during the period 2003-2008, which was very unique of its kind. The report provided a comprehensive view of the development status of the district in terms of Health, Education, Income, Employment etc. The report would be a useful tool for adopting appropriate development strategies and to address the gaps to bring equitable development removing the disparities. After the successful completion of the same, now the State Planning Commission has again initiated the process of preparation of Human Development Report based on the current status. The initiative of State Planning Commission is applaudable as this approach has enhanced the understanding of Human Development in a better spectrum.

  • Effects of the December 2004 Indian Ocean Tsunami on the Indian Mainland
    Effects of the December 2004 Indian Ocean Tsunami on the Indian Mainland Alpa Sheth,a… Snigdha Sanyal,b… Arvind Jaiswal,c… and Prathibha Gandhid… The 26 December 2004 tsunami significantly affected the coastal regions of southern peninsular India. About 8,835 human lives were lost in the tsunami in mainland India, with 86 persons reported missing. Two reconnaissance teams traveled by road to survey the damage across mainland India. Geographic and topological features affecting tsunami behavior on the mainland were observed. The housing stock along the coast, as well as bridges and roads, suffered extensive damage. Structures were damaged by direct pressure from tsunami waves, and scouring damage was induced by the receding waves. Many of the affected structures consisted of nonengineered, poorly constructed houses belonging to the fishing community. ͓DOI: 10.1193/1.2208562͔ MAINLAND AREAS SURVEYED The Great Sumatra earthquake of 26 December 2004 did not cause shaking-induced damage to the mainland of India, but the consequent Indian Ocean tsunami had a sig- nificant effect on the southern peninsular region of India ͑Jain et al. 2005͒. The tsunami severely affected the coastal regions of the eastern state of Tamil Nadu, the union terri- tory of Pondicherry, and the western state of Kerala. Two reconnaissance teams under- took road trips to survey the damage across mainland India. One team traveled from the Ernakulam district in Kerala, then continued south along the west coast to the southern- most tip of mainland India ͑Kanyakumari͒ and up along the east coast to Tuticorin. The coastal journey was then resumed from Nagapattinam, moved northward, and concluded at Chennai.

  • 1 Cuddalore District Disaster Management Plan 2017
    CUDDALORE DISTRICT DISASTER MANAGEMENT PLAN 2017 1 INTRODUCTION The Cuddalore District Disaster Management Plan for year 2017 is a key for managing disaster related activities and a guidance for emergency management. The information available in DDMP is valuable in terms of its use during disaster. Based on the instructions pertaining to the Sendai Framework Project for Disaster Risk Reduction and on the guidelines of National Institute of Disaster Management (NIDM) formulated by the Central Government and on analysis of history of various disasters that had occurred in this district, this plan has been designed as an action plan rather than a resource book. Utmost attention has been paid to make this Plan Book handy, precise and accurate. During the time of disaster, there may be a delay before outside help arrives. Hence, self-help and assistance from local group is essential in carrying out immediate relief operations. Also, reach to the needy targeted people depends on a prepared community which is alert and informed. Efforts have been made to collect and develop this plan to make it more applicable and effective to handle any type of disaster. Details of inventory resources are given importance in the plan so that during disaster their optimum use can be derived. The important rescue shelters, most necessary equipments, skilled manpower and critical supplies are included in the inventory resources block-wise. Role and responsibility of all departments have been included and the details of control room of various departments, ambulances, blood banks, public health centers, government and private hospitals have been included in this plan.

  • Assessment on Coral Reef and Seagrass Meadows Within the 10Km Radius from the Proposed Groynes Site in Keelavaippar Coast, Gulf of Mannar
    Assessment on coral reef and seagrass meadows within the 10km radius from the proposed groynes site in Keelavaippar coast, Gulf of Mannar 1. BACKGROUND The Gulf of Mannar (GoM) located in the southeast coast of India extends from Rameswaram Island in the north to Kanyakumari in the south and is important coastal area. GoM has been declared as Marine Biosphere Reserve by Government of India in 1989, covering 10,500 km2. Corals and coral reefs of Gulf of Mannar form an important ecosystem, which support a variety of commercial and ornamental faunal and floral species including fishery resources. The islands occur at an average distance of 8-10 km from the mainland. The 21 islands and the surrounding shallow water area covering 560 km2 were declared as Marine National Park. Along with corals, luxuriant and patch seagrass meadows in GoM provide high biodiversity. The Tuticorin group of islands is located at the southern tip of the Gulf of Mannar Marine National Park which consists of four islands. Among them, two coral reef islands which occur closer to the proposed groynes location. Proposed groynessites are located in Keelavipar coast and the project site comes within the Marine biosphere Reserve and about 2 Km away from the Marine National Park boundary. Tamil nadu fisheries department proposed to set up three groynes (Groynes - 1, Groynes - 2 and Groynes - 3) in Keelavaipar coast within 1 km proximity to the marine zone and these sites occurring in shore distance of 1 Km. Groynes - 1 would be covering a distance of 800 meter; Groynes - 2 covers a distance of 500 meter; and Groynes - 3 which is covering a distance of 100 meter towards marine zone.
