    This study compares the HVSR technique (Horizontal to Vertical Spectral Ratio), based on seismic event records, and the HVSRN technique (Horizontal to Vertical Spectral Ratio of Noise) using seismic noise registrations. Both methods allow us to study the amplification phenomenon of a horizontal component of seismic waves when the waves reach loose sediments in subsurface layers. The seismic data were measured at a three-component single seismic station located in the village of Tarnowek, in the Legnica-Glogow Copper District. The results of the study demonstrate that average HVSRN and HVSR maxima can be distinguished: for periods approximately 3.78 s (H/V = 6.2) and 3.969 s (H/V = 8.98) respectively. The evaluated share of the Rayleigh wave component in the recorded values was beta = 0.58 and it can be suggested that the Love wave share in surface motion was insignificant. The Love wave share remains unknown

    W artykule przedstawiono wyniki prac nad hipotezą o występowaniu wieloletniej zmarzliny w okołoszczytowej okolicy Babiej Góry. W badanym obszarze wykonano trzy profile inwersyjnego obrazowania oporności, których maksymalna głębokość interpretacji sięga do około 90 m pod powierzchnię gruntu. Uzyskane wyniki nie potwierdzają jednoznacznie występowania permafrostu w badanym terenie, natomiast dobrze ukazują budowę geologiczną szczytowych partii Babiej Góry
