Title: Detection of several P wave velocity models based on artificial earthquake records
Abstract: According to the surface wave calculation of different crustal velocity models of the Fujian area(Rayleigh wave and Love wave),compared with the surface wave Green function extracted from the noise records observed on the sames line,this paper evaluates the fitting degree of model surface waveform and actual observation noise surface wave Green functions,and qualitatively analyses the reliability of each crustal velocity structure.Then combined with the noise data of seismic network of Fujian Province,this paper studies the surface wave Green function extracted from noise records,according to the characteristics of surface wave,which is more sensitive to the underground layered velocity structure.Through the comparative analysis of the waveforms(Rayleigh and love) of theoretical surface waves calculated based on different crustal velocity models of the Fujian area and the surface wave Green functions extracted from noise records observed on the same measurement line,this paper summarizes the advantages and disadvantages of various models and determines what kind of model is applicable in the area of Fujian.
