The authors thank Dr. Yuzo Shinozaki for his discussion and the answers are as follows. (1) The authors think that the investigated incident wavefield; plane SH wave propagating along the fault axis with vertical incident angle of 45° and 0°, is reasonable considering the radiation pattern of the source mechanism of the earthquake. The SH wave incident analysis in the original paper does not mean the 2-D anti-plane analysis (2) The hyperelement method is adopted to show the ground motion amplification due to the deep irregular underground structure by using possibly simple model at earlier stage investigation because of the computational efficiency in spite that the method reduces the degree of freedom of modelling of actual geologycal structure. One another reason why the authors selected the method is that the scattering wavefield can easily be decomposed from the total wavefiled. (3) The authors think that the ground motion amplification characteristics based on the discussor's model cannot be applied to a discussion of the interpetation of the heavily damaged belt zone because the model is quite different form the geological structure in Kobe City. (4) As for the indicated publications to several journals, the authors had no intention of multiple publications, but they intended to appeal the idea to many persons of various fields; not only earthquake engineers but also seismologists, and not only Japanese but also persons in the world through the journal with world wide distributions.
