Rama Setu: geo-environment ignored in SSCP The disastrous aspects of Setusamudram Channel Project (SSCP) relate to the fact that tsunami effects were not taken into account and that no tsunami protection measures have been incorporated in the project.
Another serious lapse in project design of SSCP is that Geological Survey of India (GSI) has NOT been consulted. GSI has a marine wing and is fully equipped to render technical and scientific guidance.
It is shocking that such an agency was not involved to review the geo-tectonic and geo-thermal situation in the project area. This lapse alone should render the Govt. of India to stop further work on the project until the many concerns raised by earth scientists are properly considered and evaluated.
Rama Setu region is as intense a geo-thermal region as the Himalayas with the thermal energy emanating from the inner core of the earth. The possible impact on the geo-thermal structures by the dredging activity should be carefully evaluated before embarking on the project.
Geological Survey of India – one of the oldest surveys in the World is a premier organisation of Earth Science Studies in the sub-continent with a strength of 2100 geoscientists and technical professionals and is mandated as the nodal agency to clear development projects like SSCP.
Geological Survey of India (GSI)
The Department of Mines has jurisdiction over Geological Survey of India and Indian Bureau of Mines, both of which are subordinate offices…The GSI is the principal agency responsible for the assessment of geological and regional mineral resources of India. GSI was established in 1851 and is one of India’s oldest investigative agencies in the field of earth sciences. Its areas of operation encompass scientific surveys and research, for locating mineral resources. GSI operates through six regional offices and four specialized wings – marine, coal geophysics, airborne surveys and training.
The GSI has to its credit geological mapping, covering an area of approximately 3.146 million sq.km, or 94 percent of the area of India. The maps are on a 1:63,360/ 1:50,000 scale, the data having been synthesized to produce 1:2000,000 scale geological maps of India, which have been correlated with the global set up as per international standards. The GSI is also actively involved in the research and development of mapping and exploration techniques. It has set up a chain of modern petrological paleontological, chemical, mineralogical, geochronological, geotechnical and geophysical laboratories in its different operational bases, and offers its facilities and services on payment. Geological maps and data are available with GSI on a commercial basis. http://www.indiacore.com/mining2.html
Providing critical geoscientific inputs to developmental projects 5.20 The fields of activity under Engineering Geology has undergone sea changes in recent years with renewed emphasis on hydro power and river linking projects. Additional geotechnical inputs are required for underground storage facilities for gas and crude oils.5.21 Geological Survey of India has been associated with almost all the major irrigation/water resource development, transport, power and miscellaneous civil engineering projects and is responsible for providing geotechnical input to various geological problems in preliminary, pre-construction, construction and post- construction stages of the projects. GSI works in close collaboration with the major executing bodies, like Central Water Commission, State Irrigation Department, State Electricity Board, Public Works Department, Defence Organisations, Public Health Engineering Departments, etc.The endorsement of the Survey has become a prerequisite for ultimate sanction of any project, particularly a multipurpose project. The advice rendered by GSI not only helped in successful completion of various projects, but also aided in saving of cost and time by avoiding unnecessary post-construction remedial measures.

Chennai, June 13: Janata Party president Subramanian Swamy …On Ram Sethu issue, he said the present canal alignment chosen by the UPA government in the Sethu Samudram Project which necessitated the destruction of Ram Sethu was not cleared by the Indian Navy. Hence, he demanded the Defence Ministry to review the present alignment. http://newstodaynet.com/13jun/ld6.htm Q & A by Cho Ramaswamy R Rajadurai, Sirkali Question: Why do you think that the Dravidian parties which have accepted the existence of Ravana – [the villain] of Ramayana as one of their own – are insisting on saying that the Ram Sethu is a myth?Answer: According to the “rational” Ramayana – Ravana is real while Rama is a myth. If someone were to call the bridge linking [Rameshwaram] and Sri Lanka as the “Ravana Sethu,” who knows, it might be accepted as a “rational reality!” http://indiainteracts.com/columnist/2007/06/12/Q–A-by-Cho-Ramaswamy/
