Study on the near-field ground motion of Fukuoka earthquake by the method of computing Greens functions for a layered half-space
The slip distributions on the fault, the source rapture process and the other seismic parameters of Fukuoka earthquake determined by Japan researchers are accepted in this paper. The station Genkai is chosen as a site to analyze the Fukuoka Earthquake wave in near field by using the Greens function method for a layered half-space. A comparative study of the acceleration time history of the calculated results and records are carried out. The waveforms of the calculated results are in good agreement with those of the observed records at the station Genkai, and the peak values in the calculated results are close to that of the records. The Fourier spectra of the calculated acceleration time history are basically identical with those of the records while the frequency is below 5. Some useful conclusions are drawn that the near-field ground motion of Fukuoka earthquake can be effectively estimated by the method of computing Greens functions for a layered half-space in the condition of the uniform geologic site. The seismic parameters of Fukuoka earthquake are helpful to study the near-field and far-field ground motions and the influence on eastern China including Shanghai.
