I would like to monitor the movement and behaviour of the rocks below 10 km or above from the surface. At such the depth what will be the stress and strain can be handle by the rocks.
Yes of course, it is worth to study deep crustal structures but it is not as easy as we think. To do this worthwhile research, we need to have enough facilities and equipment. Furthermore we need to have skilled professionals to interpret the obtained data. As you know, the best instrument to analyze the deep structures and activities is geophysical methods which are almost complicated but nothing is not impossible and "impossible is just impossible". You can do it if you decide to do it !
@Rahim thank you sir for your valuable response. As I am new researcher I would like to know more depth detail. So I can start my research by solving the problems or listing out the difficulties which I have to minimise.
To start with, search out the research centers and universities who are doing similar kind of work. Read their publications thoroughly. Meet them in person and discuss if possible or at least via mail. As Mr Rahim suggested you will need sophisticated instruments and expertise to take up this work, try to join a good institute based on your inventory, even if it is less paid, if you are really interested. In this way you can get an experience of instrument handling and data analysis under the supervision of experts. Further, once you recognize the possibilities and identify limitations, you can go for doctoral research at an appropriate institute in India or abroad.
