In order to study effects of site conditions on damage to structures during an earthquake, an evaluation of geotechnical parameters and physicomechanical coefficients of shallow depth strata of Bam city, located in southeast of Iran, is accomplished. Seismic refraction and vertical seismic profiling (VSP) data are collected along the region. Acquired parameters are Vp/Vs, resonance amplification and quality factor (Q), and contour maps are plotted for each of them. These contour maps are compared with destruction maps of the Bam city earthquake in the region. This comparison reveals a good correlation between the destruction zone and the identified regions in this study.
