A shear wave velocity structure model of Padang, Indonesia was developed and the site amplification characteristics of earthquake ground motion were examined. The presented shear wave velocity structure model was obtained based on the microtremor survey. The inversion analysis of the dispersion curves of Rayleigh wave were performed for 11 sites where the array microtremor observations with 4 sensors were done and the shear wave velocity profiles were estimated for these sites. Furthermore the peak periods of HVSR for 130 sites were obtained and the distribution of the site dominant period was shown. The 3D shear wave velocity structure model was developed by considering the relation between the shear wave velocity profiles of 11 array sites and the site dominant period distribution. Finally the site amplification effect was investigated by conducting the finite element analysis.
