Analysis on the Reliability of the Earthquake Rupture Process Inferred from Near Source Waveforms

摘要: Several numerical tests have been analyzed in this paper to discuss the influences from uncertain parameters of presumed inversion fault model. The influence data resolution results has also analyzed. We discussed time length and distribution observational stations. Our research indicates: (1) near-field waveform can well reveal source rupture process shallow part fault, however, it poorly constrains slip on deep fault. Jointly using near- far-field provide more complete message whole (2) result is very sensitive strike dip 2° deviation for 5° angle that true will lead a distorted result. (3) media structure Chi earthquake faulting might be ignored if we take difference between Ma's model Wu's as measure uncertainty.
