Shear wave velocity, soil density and standard penetration test value in depth at 35 boring points in Nagoya area were measured by means of P and S wave-velocity logging up to about 100m in depth. The empirical equations for estimating shear wave velocity and soil density were derived on the basis of these underground data as well as soil characteristics. By making use of these equations and boring data (depth, standard penetration test value, soil age and soil facies), shear wave velocity and soil density in depth were estimated. By means of multi-reflection method of shear wave, transfer functions at about 280 mesh points in Nagoya area were calculated, and distributions of maximum amplification factors and predominant periods were obtained. It was found that maximum amplification factors were large and predominant periods were long in the western part of Nagoya area. The relation between the maximum amplification factor, and the damage ratio in the Nobi and the Tonankai Earthquakes was studied, and it was clarified that the larger maximum amplification factor the greater damage ratio bacame.
