研究地震活动规律是预报地震的最重要途径。自从古登堡(B.Gutenberg)和里克特(C.F.Richter)发现地震序列中震级与频度具有对数关系:lgN-a—bM之后,“b”值变化一直被用来预报地震。但上述关系只是序列总体的平均统计结果,未能指出序列内部的结构特征。因而用“西”值预报地震带有不确定性。 本文通过对新疆西部地区浅源地震活动序列分析,首次发现一定强度的地震活动序
Studying the law of seismic activity is the most important way to predict earthquakes. Since Gutenberg and C.F. Richter found that the magnitude and frequency of earthquakes have a logarithmic relationship: the change in “b” has been used to predict earthquakes since lgN-a-bM. However, the above relationship is only an average statistical result of the overall sequence, failing to indicate the structural features within the sequence. Therefore, using the “West” value forecast earthquake with uncertainty. Based on the sequence analysis of shallow-sourced seismic activity in the western part of Xinjiang, this paper first found that a certain intensity of seismic activity sequence
