Spectra of seismic noise as recorded by vertical channels of KS-1 and STS-2 seismometers.

The spectrum of earth tides as recorded by the KS-1 three-component superbroadband seismometer installed at the Svitino seismic station. The absence of daily harmonics on the NS component is due to the station's geographic location.
