Methods of Determining the Seismic Spatial Distribution Functions

摘要

Several factors are selected to reflect the temporal and spatial features of seismicity in Southwest China.The measurements of the factors are all taken from the statistical relation between the factors and actual earthquakes,and make the factors possess a certain probabilistic prediction meaning and the base for mutual contrast.The effects of prediction of part of the factors have been evaluated and used to correct the factors.Three sets of seismic spatial distribution functions have been calculated by using three different methods and discussed in detail.
