- Abstract:
- By analyzing the earthquake activities in the tectonic regions of the Chinese mainland,Qinghai Tibet plateau,Xinjiang,north China,and northeast China,it was demonstrated that the regional earthquake is a kind of SOC phenomena.The fractal characteristics and trans-scale features of fractal structural of faults in Chinese mainland and tectonic regions were researched comprehensively with the macroscopic grid method in fractal theory.According to the experiments result of sand pile model with fractal features and the fracture mechanics,it was suggested that the SOC phenomena of earthquake is associated with the SOC dynamic process of fractal geometry faults.There is a positive correlation between the fractal dimension of faults and earthquake.The causal relation between faults fractal and earthquake fractal was clarified.Base on the preceding conclusions,a hypothesis was proposed that the system output energy fractal is based on the fractal structure of system.Further analysis was carried on with existing observation data.Finally,based on this hypothesis,and also the fact that the region faults distribution can be determined by aerial and satellite shot,ground survey and geologic exploration,it was proposed that the probability distribution of regional earthquake can be estimate with the positive correlation of the fractal dimension between faults and earthquake.The results can be helpful for earthquake prediction.
