CHARACTERISTICS OF SEISMIC NOISE AT PERIODS NEAR 1.7S
ACCORDING TO DATA OF STATIONS LOCATED IN NORTHERN TIEN SHAN
I.N. Sokolova, N.N. Mikhailova
Institute of Geophysical Research NNC RK, Kurchatov, Kazakhstan
Detailed analysis of dynamical characteristics of seismic noise in storm days and calm days in Issyk Kul Lake was
done for 25 broadband seismic stations installed on the territory of Kyrgyzstan. All stations show sharp increase of
spectral density of seismic noise in periods range from 1.3 to 2.5 s during storm days in comparison with calm days, and
show decrease with distance according to logarithmic linear law.
