摘要:: 通过对2006年山东省地震电磁扰动监测台网的电磁扰动异常资料的分析,定义了地震电磁扰动异常信息量S,并用来定量研究异常信息的特征。结果表明,S值大小可能与地震的震级有关,并且反映了区域应力场的活动强度和研究区f域的地震活动。最后从物理机制和震例两个方面对S作了进一步论述。

Abstract:: We analyze the abnormal data observed by Shandong Earthquake Precursory Electromagnetic Disturbance Observational Network and quantitively study the abnormal characteristics with the definition of the electromagnetic disturbance abnormal information S.The results show that S reflects the earthquake activity and intensity of the stress field and has related to the potential earthquake's magnitude.Further,we also discuss S on the physics and other example of the earthquake.
