In this paper, we proposed the extended formulation of Hisada's technique to the problem of Love wave incidence to the vertical interface between the multi-layered media and the half-space. With the use of the representation theorem, the displacement field of the layered media is expressed by the displacement and stress on the vertical interface. The normal mode solution is used for Green function. Combining this procedure with Hisada's original method, we demonstrated the seismic response analyses of shallow sediment-filled valley and checked the validity of our approach in comparison with results from other method. We confirmed that our approach has some advantages to make better understanding of the seismic characteristics in such geological structure.
