Here, the site effects of seismic hazard zonation of urban areas on the ground motions and earth deformations is studied in Shahrekord. The main purpose is zoning the geological engineering features and assessing the seismicity of the region. In this regard the microtremors are measured by single point sampling method and Nakamura analysis. The microtremors of all over the city are processed by J-SESAME. The information layers are prepared in GIS used for detecting the zonations of potential landslide hazard. Shear wave velocity is calculated in ۲۰ profiles for soil classification. The microtremors are measured in ۶۵ points and ۷۰ wells and boreholes. To study the earth deformation, geological engineering condition is investigated using Digital Elevation Model (DEM), slope, slope orientation, soil type, soil thickness, underground water, rockfall and liquefaction maps. The natural period of site and amplification factor are analyzed using microtremor and shear-wave velocity.
