Mapping the resonant frequencies of upper geological layers in the locality of Zlaté Hory is presented in this paper. This study follows from the results of seismological measurement performed in the locality during a winding tower demolition in the year 2011. Significant harmonic vibrations were recorded in the vicinity of the tower during the demolition. Based on the seismic noise measurements, resonant frequencies of upper geological structures were determined and analysed together with the results of geophysical measurements and borehole documentation. This result has confirmed the hypothesis that harmonic vibration recorded during the tower demolition represents resonant vibration of soil and weathered rock layers in the near zone of the tower.
