Based on the size of correlation coefficients between scanning curve and source region curve, the authors analyze quantitatively the difference of scan results of different slip modes and study the impact of fault strike in different tectonic divisions on seismology parameters scanning results and variation rules. The results show that not only the change of spatial parameters has great influence on the seismological parameters scan, but also the fault strike in source region. This paper presents the optimum condition parameters with least influence space scope in scanning for different magnitude seismology indexes and analyzes the possible influence of fault strike on scanning results of seismology parameters.
