In this paper is presented the study of site response parameters of AlbanianSeismological Stations (ASN) from ambient noise measurements and felt earthquakes.Theseismological stations of Albania which use the VSAT communication technology are locatedgenerally in hard rock formations.The aim of Methodology is to compare the response parameters of the sites (fundamentalfrequency, amplification) for registered seismic signals, from microtremors and the earthquakes as well.The predominant frequency of the site of every seismological station site is determined usingthe methodology of Horizontal to Vertical Spectral Ratio (HVNR), of the triggered noise and severalfelt earthquakes in Albania territory.From the results of this study, is concluded that fundamentalfrequency (F0) and the amplification in this frequency (A0), are almost the same for the microtremorsand seismic events.As far as for the amplification factor, we concluded that on the sites ofseismological stations situated on hard rock (basement) there is not amplification.In the contrary, forthe Vlora station site, the amplification factor is 5" at fundamental frequency 6 Hz, showing that thisstation is not situated on the hard rock.The microtremors are a useful technique for the siteassessment effects, used in microzonation of urban areas, that complement the lack of seismic data ina region (boreholes, geology, etc.
