摘要
本文研究了1983年菏泽5.9级地震前后聊考带两侧50公里范围内地震活动归一化熵值的时、空分布特征,从而得出震前熵值变化出现明显低值异常的结论,并根据震后熵值变化特征对该区震情趋势作了估计。
The time-space distributive characteristics of normalizing entropy value of seismic activities within 50 kms on both sides of Liaokao fault before and after the Haze earthquake (Ms5.6) in 1983 have been studied in this Paper and thus it is concluded that the variation of the entropy value before the earthquake (Ms 5.9)showed an obviously low value anomaly. Based on the characteristics of entropy variation after the earthquake, the seismic tendency in the region was estimated.
