The geographical information system to construct the dynamic soil model in urban area using existing soil data is demonstrated. Based on the regression analysis, the empirical equations to evaluate shear wave velocity and weight per volume are derived. By using these equations, the dynamic soil model can be obtained at the arbitrary point in Nagoya area where PS logging data or boring data do not exist. The method of dynamic soil modeling is installed to the disaster prevention geographical information system. In this system, the dynamic soil model at arbitrary point in Nagoya city is generated so that the predominant frequency and soil amplification is interactively evaluated.
