SPECTRAL CHARACTERISTICS OF SEISMIC AND INFRASOUND NOISE BY DATA OF THE MONITORING NETWORK STATIONS OF THE NATIONAL NUCLEAR CENTER OF THE REPUBLIC OF KAZAKHSTAN

The spectral characteristics of seismic and infrasound noise were calculated by the waveforms of the NNC RK network stations using PQLX software. The calculation results were compared with the seismic noise model by Peterson and infrasound noise by Brown. The daily and seasonal noise variations were analyzed. Special attention was paid to regularities of the level change at microseismic maximum. The observed peculiarities are well explained by the location and dynamics of microseism and microbarom sources located in the North Atlantics.
