the fractal geometry is applied to studying the active faults system in Guangdong Province. Results indicate that the spatial distribution of all faults in Guangdong Province is a distinct fractal set with selfsimilarity in the nonscale range of 12.5-100 km
and the fractal dimension
obtained by the boxcounting method
interprets well the characteristics of the spatial distribution of faults. The fractal dimension of all faults in the study area is 1.582 3
that of the NE faults 1.434 2 and that of the NW faults 1.115 7 and EW faults 1.039 4. The densities of spatial distribution of the NE and the NW faults supplement to each other
indicating the inter-restraint properties of these two groups of faults. Eventually
correlating the isoline maps of fractal dimensions and historical earthquake distribution
it is tried to find out the relationship between the fractal characteristics and seismic activities.
