Abstract: By taking medium-strong earthquakes of South China,North China and western China as the research objects,this paper selects 8 kinds of seismology indexes with clear physical meaning and strong independence to carry out spatial scans of the parallel slip,vertical slip and oblique slip along the fault strike,respectively. Based on the size of correlation coefficients between scanning curve and source region curve,we 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.
