| Abstract: | A study was made on temporal sequence of the earthquake swarm with M6. 7 which took place in Batang County, Sichuan Province, from April to Sept., 1989. Temporal sequence of the swarm was characterized by obvious sectional release process, in dex rise of creeping curve, certain order behavior among the peak values in the early sequence, transient tranquility before strong aftershocks and abnormal high values in sequential entropy. Subsequence of the swarm were represented by the forms of isolation pattern and mainshock-aftershock pattern,changed from the former pattern to the latter and characterized by fast-slow-fast attenuating pattern. According to time fractional dimension calculation results of the swarm sequence and the subsequences, it was discovered that non-scaling regions existed in the complicated temporal sequence structure, the span of non-scaling region of capacity dimension Do was different from that of the information dimension D1 of the same sequence, and the self-organizational features of the same sequence were different when various magnitude threshold values were selected for calculating. From the stochastic non-uniform spread of swarming high fractures in the seismic regions, it was primarily explained that the exponential attenuation of time sequence variation was likely to occur.Meanwhile, the level structures of various order sequences of the strong seismic swarm and the order problems were discussed. |
