Abstract
The wide-angle seismic reflection/refraction data analyses play important roles in determining lithospheric scale crustal structures and understanding tectonic processes in the lithosphere. The structure analysis is an intrinsically nonlinear and often an underdetermined problem. Therefore, several subjective analysis processes are usually required for modeling lithospheric scale structure. Generally, subjective analysis processes reduce the credibility of the resultant models and we cannot discuss fine variation of the obtained structure models. Recently, the increasing the quality and quantity of the seismic data as well as the increasing the computer power has enabled us to apply advanced and objective structure analysis approaches and to discuss the detailed structure variation. In this paper, I show my developed and adopted structure analysis approaches and software tools for constructing the lithospheric scale crustal structure models objectively.
