Summary/Abstract: The present study investigates the characteristics of seismic sites of some of the NOTSSI monitoring network stations, based on microseismic noise. Nakamura's method of the spectral ratio of the horizontal to the vertical components of the seismic noise (H / V), directly related to the S-wave velocity of distribution (Vs) at the observed site was used for calculating the station repairs. The spectral H / V ratio of the seismic noise for 11 seismic stations is calculated, combined with geological data bellow each station. The values of A0 - site-effect, f0 - resonance frequency and h - depth of reference at the most contrasting resonance boundary were obtained. Attention is paid to seismic instruments and sensors
