Analysis of ground motion directivity was performed for the studied undermined area of Stonava (Czech Republic). The resonant frequencies calculated from the seismic records at permanent seismic stations and the resonant frequencies obtained by analysis of seismic noise measurements are represented by the spectral ratio peak of about 1 - 2 Hz. Records of seismic noise were used also for the elaboration of H/V spectral ratio as a function of azimuth and the determined direction of maximum amplification was compared to the local tectonic structure and stress conditions.
