Abstract
In the urban seismic disaster mitigation or the aseismic design of building, it is essential to evaluate seismic ground motion properly. The geographical information system QuSE (Quickly Seismic Evaluation system) is newly developed here. QuSE has three main funtions which are the evaluation of seismic ground motion for virtual fault, the identification of active faults which affect any specific site, and the evaluation of seismic risk for arbitrary return period at any specific site. In order to evaluate the seismic ground motion properly, QuSE combines seismic related data, soil data and the various empirical formulas on Giographical Information System (GIS).
