摘要
本文从现代统计物理学中熵的概念出发,用所定义的合成缺信量和地震活动信息熵的方法,讨论了中国西南地区永善、龙陵二次强震前后地震活动的信息和信息熵,采用时间域、空间域以及空间扫描三种不同的分析方法,结果表明,强震前缺信量的降低和信息熵的减熵过程是明显的,并且具有熵值下降过程中发震,随后熵值恢复的孕震模式。
Starting from the entropy concepts of the modern statistic physics and using the sythesized value of information absence and the seismic information entropy defined in this paper, the authors discuss the information and information entropy of the seismic activities respectively before and after the strong Yongshan and Longling earthquakes occurred in southwestern Yunnan Province. Three methods are used in the analysis, namely, the time domain, space domain and spatial scanning methods. Result of the study shows the pre-strong-earthquake periods are associated with evident processes of decreases of the value of information absence and the reduction of information entropy. It is also concluded that the seismogenic processes arc mostly associated with earthquake occurrence in the course of entropy reduction and that the entropy value tends to return to its normal value after the earthquake.
