The main items discussed in the present paper are as follows: 1. Why did the authors assume plane SH waves as an incident wavefield though the heavily damaged belt zone is situated just above the fault sources? 2. Hyperelement method developed about 20 years ago is less applicable to vertical as well as horizontal boundary value problems of deep irregular underground structure than the conventional methods such as FEM and FDM. Why did the authors choose a hyperelement method? 3. Though there was very few earthquake acceleration records observed in the heavily damaged belt zone, the authors concluded without any verification that simulated peak acceleration distributions coincide with roughly estimated observed distributions of structural damages. 4. The authors performed multiple publication.
