This paper presents an analysis of a seismic response of shallow geological structure beneath seismic stations in Książ (KSP), Ojców (OJC) and Górka Klasztorna (GKP) by means of the HVSR (Horizontal to Vertical Spectral Ratio) technique. This approach, developed by Nakamura (Q Rep Railway Tech Res Inst 30:25–33, 1989), allows to estimate the amplification effects due to coherent summing up of the direct and multi-reflected waves, while analysing spectra of horizontal and vertical parts of seismograms. This preliminary attempt to estimate the amplification effects is based on an analysis of seismograms from both mining induced and teleseismic earthquakes. The results show that amplification factor is less than 2 for all considered stations, suggesting very weak site effects. The HVSR curves for induced seismicity and for natural earthquakes are similar but not the same. The difference is visible at low frequencies, where the amplification effect estimated on the basis of local seismic records is apparently larger than for the teleseismic events.
