中强地震前电磁扰动异常信息量S的分析

Analysis of the Quantity of Electromagnetic Disturbance Abnormal Information S before the Medium-Strong Earthquake

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。

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 electromag- netic 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.
