Resonant frequency and its changes in the surroundings of the permanent seismic station in the village of Stonava have been studied in this paper. Three different sets of seismic events were elaborated: local mining induced seismic events, distant earthquakes and seismic noise. Two data sets recorded at the permanent seismic station STO2 were used for spectral ratio computation using the HVSR method. First data set contains 20 records of mining induced seismic events with maximum epicental distance of 4 km. The second data set contains 7 records of intensive distant earthquakes. Third data set was used for spectral ratio computation using the HVNR method. This data set contains records of seismic noise, that was measured at 18 places on the profile of the length of 2 km.
