Chennai is badly planned city. No open space. Everywhere buildings and building construction. people park their vehicles on the road and block the road. In this situation if an earthquake strikes, rescue (of course by our army/paramilitary) will not be impossible and people have to die below the concrete. Bad city planning, population explosion and migration of people from rural to urban and lack of civic sense and orderliness among people actually kill people and not earthquakes. Earthquake is a natural process by which energy accumulated in certain areas below the surface is removed, like we remove our angle and cool down by bursting out. If any fool tells that chennai, bombay and other areas are not earthquake prone, do not believe that fool. I strongly believe that a major earthquake is due for Chennai, Bombay areas.
