Multiple seismics does not only complete and make more precise structural and physical parameters of a geological section but also serves as a basis for formulating tectonophysical problems on prediction and calculation of stresses at each point of a section. Moreover, velocities of P- and S-waves in the layers, their density and configuration of seismic boundaries permit the stress field to be related to displacements of a free surface which are instrumentally observable, i.e., to recent movements.
