By: M.S.Yatnatti: Editor and Video Journalist Bengaluru: Government of India should plan in a way that its citizens are protected from earth quakes .It should not develop new cities in seismic zones level five .Develop smart cities in non- seismic zones.Government of India should start shifting its vital installations and buildings from high seismic zones and shift them to safer places. The Safety Element of the General Plan is required by State law. It specifies policies applicable to new development and outlines programs that County government should implement to help improve public safety, particularly during times of natural or human-caused disasters. New Development need to be Generally Prohibited - New development shall be prohibited in Geologic Hazard Zones, unless a site specific study, based on original work by a qualified Registered Geotechnical Engineer, certifies that the area proposed for the new development is free of hazardous conditions. The County shall use the current Geologic Hazards Database in the County Geographic Information System (GIS), as illustrated on the following maps, to identify areas susceptible to geologic hazards. Minimize the potential for loss of life and property resulting from geologic and seismic hazards. The problem has to be untangled with a holistic approach where structural engineers, architects, urban planners, local authorities and the local community participate, not only in reducing existing vulnerability but avoiding the construction of new seismic risk in the future. In order to study the discrepancy between urban zoning regulations and seismic codes with regard to vulnerable modern building configurations and the causes of the international dissemination of architectural and urban planning concepts that generate vulnerability in contemporary cities, historic research was developed
Our scientists need to work on productive projects instead of wasting their energy time and government of India research money in wasteful projects. Reportedly French engineers have been experimenting with a technique that could redirect seismic energy away from structures such as cities, dams, and nuclear power plants, sparing them from damage. It involves digging large, cylindrical boreholes into the ground, forming a defensive geometry of lace-like arrays that, researchers hope, could deflect seismic waves and thus make whole landscapes "invisible" to earthquakes. Interestingly, the deflected seismic energy wouldn't just disappear: another city, town, or empty landscape that would not previously have been affected could now very well experience the brunt of the destruction. There are some other implications here, then, including the potential need to designate--or even design--a kind of seismological sacrifice zone where these quakes could be directed. Like seismic weapons, these drilled grids of empty space on the edge of the city would thus be used to send earthquakes toward other locations. Think of them as magnifying lenses in the ground for redirecting seismic destruction.Or you find the places which are earth quake resistant and build the cities around it.Quake-resistant buildings, an expression being widely used these days, refer to buildings that are designed to withstand the shock of earthquakes and not crumble. Depending on the seismic zone they are in, buildings are constructed to withstand a certain magnitude of earthquake. But earthquake-resistant is not earthquake-proof. Faced with earthquakes of higher magnitudes, they would go down.The key idea in making a building earthquake-resistant is to make it ductile, that is, to give it a certain flexibility to shake horizontally. Stiff buildings, when faced with earthquakes, would go down, but the flexible ones would sway and come back to their original position. The idea is to soften the impact of the earthquake, and to let the building absorb the energy.Most of the newer high-rises these days, especially those in the high-seismic regions, are constructed to withstand the impact of earthquakes of up to a certain strength. Older buildings can also be retrofitted with technologies to make them resistant, even though it involves investments of time and funds. It makes sense to build an earthquake-resistant building -- experts say the cost differential in newer buildings is not more than 15 to 20 per cent of the original cost. Retrofitting, on the other hand, might be more expensive.India is very prone to earthquakes as well. The major reason for the high frequency and intensity of the earthquakes is that the Indian plate is driving into Asia at a rate of approximately 47 mm/year. As per the Geographical statistics, almost 54% of the land in India is vulnerable to earthquakes.According to the estimates shown by a World Bank and United Nations report; around 200 million city dwellers in India will be exposed to storms and earthquakes by 2050.
