Is India ready for an eighth-magnitude earthquake near a metro?

The tragic earth quake that has hit Nepal is a warning for all of us in India. It has been said that earth quakes don’t kill, but falling buildings do. Ours is a country notorious for its inability to enforce building codes. Politicians and bureaucrats have made a mockery of building codes. Irregularities are there in the majority of buildings. Laws are enacted to “regularize” malpractices by paying some money. 
Malls are allowed to come up in the middle of cities without adequate parking. The roads are overloaded. The sewage system gets overloaded making most malls “the stinking malls” of India.
In the midst of all this, some cities are planning to encourage very tall buildings, allowing a floor space (FSI) index as high as 6 or more! What will happen if a major earthquake hits a metropolitan city, killing several hundred thousand people? 
Whose responsibility is it to mitigate such a disaster by tightening up on the inspection of buildings and eliminating corruption? Who will review the accountability of traffic management authorities and fire services? Who will ensure that they are allowed to operate without interference from corrupt politicians? Who will ensure that architects, builders and authorities who give occupancy certificates are held accountable long after the buildings are complete?

This article reports that 80% of Delhi's buildings cannot survive a major earthquake. Most people do not know that
there are standards and guidelines for making buildings resistant to earth quakes. These are applicable to home builders too.
