摘要
本文采用历史地震分布的最大熵原理对川西中部历史地震资料进行分析,得到该区中强地震重现期和发震概率。利用现今四个地震活动带(区)小震资料,计算了地震频度的联合熵和互信息,并对1971年始至今18年小震活动资料作了内检验分析,结果表明有一定预测效能。
The historic earthquake data of the central part of west Sichuan Province have been analyzed in this paper by using the maximum entropy principle of the historic earthquake distribution to obtain the recurrence time-interval and probability of moderate and strong earthquakes in this area. Current microseismic data of four seismic zones have been used to calculate the combined entropy and mutual information of the earthquake frequency that have internally been tested with microseismic data of 18 years since 1971 to the present. The results show a certain prediction efficiency.
