SPECTRAL FEATURES OF THE MICROSEMIC FIELD OF THE URBANIZED TERRITORY
View through CrossRef
Currently, seismic monitoring is considered as a geophysical technique for recording and determining earthquake parameters. This determines the distribution of such type of monitoring in seismic areas. At the same time, seismic signals carry important information about various natural phenomena and the human impact on the environment. Registration of microseismic vibrations allows to determine the resonant features of the soil strata, which can enhance the vibrations during earthquakes, as well as during the operation of various mechanisms, causing structural damage and such a phenomenon as vibrational liquefaction of clay soils. The paper analyzes the data of long-term observations of microseismic noise in an urbanized area by the network of seismological observations Vladikavkaz and mobile stations. Daily variations of the microseismic field are shown and a map of the predominant frequencies of microseismic vibrations due to the influence of ground conditions is compiled.
