Ray Tomography on Creeping-Waves

P013 DIRECT AND INVERSE PROBLEMS OF RAY TOMOGRAPHY ON THE CREEPING WAVES Ray tomography widely applied in the global seismology exploration geophysics and seismic engineering usually uses body waves. The surface waves are employed rarely partly because of their more complicated cinematical and dynamical properties. However it is possible to point out the problems which effective solution could be gained only by the surface waves ray tomography. In the paper we consider by means of the numerical modeling the travel time inversion of the creeping spiral waves. This waves are able to transit along the curved interface for a long
