Long-term observations of lithospheric deformations were car1·ied out in the frequency range of $5\cdot 10^{-6}$ to 103 Hz in the Northern Caucasus at the Baksan Geophysical Observatory (Shternberg Institute of Astronomy). Observations were made Ьу means of an underground laser interferometer-deformograph with а baseline of 75 m. The obtained estimate of the spectral density of deformations determines the background level of seismic noise over а wide frequency range.
