Abstract

There are fractal character and fractal dimensions with time in crustal deformation field of seismogeny process. The occurrence of strong earthquake is after the process of the dimension lowering, entropy decreasing and ordering, the fractal dimension, entropy value and order degree are all resumed normal datum after the occurrence of strong earthquake, it reflects the evolution of crustal deformation field is the process from the homogeneous deformation—heterogeneous deformation—disturbance—homogeneous deformation. We regarded the fractal dimension, information entropy and order degree as pattern dynamics parameters of crustal deformation field to use, and the deformation localize process is quantitatively described by the parameters.

Key words
