Focusing Transformations - The Reliable Way To Search For Safe Location For Nuclear Waste Disposal

At present pre-stack migration is widely used in seismic data processing in order to get wave image of<br>a medium under investigation. Of course it is rather time-consuming procedure but its application is<br>justified by necessity to deal with complicated geological structures and to recover them as completely<br>as possible. The paper is devoted to the approach to pre-stack migration of multicoverage seismic data<br>by means of diffraction and focusing transformation in application to the problem of careful geological<br>investigation of consolidated rocky blocks in order to choose as safety as possible location of nuclear waste<br>deposit. Results of some real seismic data processing gathered at Nijnekanskaja area near Krasnoyarsk<br>city, where a granite block is searching for as a suitable candidate for disposal of radioactive waste, are<br>presented and discussed.
