一九七六年四月六日和林格尔六·三级地震和七月二十八日唐山七·八级地震是我台电感地应力投入观测以来华北地区发生的两次最大的地震。为了从地震事件中加深对地震孕育,发生过程的认识,提高分析予报能力,我们整理了长治台七五年以来的电感资料,从分析孕震应力场着手,对长治台附加应力状态做了初步的解释并在此基础上探索了短期予报的方法。
The 6th magnitude earthquake of 6 April and the Ringling earthquake on April 6, 1976 and the July 8th Tangshan earthquake of July 28 were the two largest earthquakes that occurred in North China since the station was put under observation. In order to deepen the understanding of earthquake inception and occurrence process and improve the ability of analysis and reporting, we have compiled the inductance data of Changzhi Station since 1975, analyzed the stress field of seismogenic shock and made additional stress state of Changzhi Station Preliminary explanations and on this basis to explore the short-term method of reporting.
