电磁脉冲数值异常初探

Variation of Gravity Field before and after Ms4 3 Earthquake in Taiyuan and Ms4 4 Earthquake in Lingshi

用ＤＷＭＪ－８９Ａ型电磁波记录仪记录的异常与地震３要素的关系，讨论了判别电磁波脉冲数值异常的方法与地震预报的问题。

The paper analyzes the variation of the gravity field before and after the Ms4 3 earthquake at Taiyuan on June 26,1993 and the Ms4 4 earthquake at Lingshi on April 26,1994.The author suggests that the obvious trend anomalies of the gravity field in the middle and the south of Shanxi occurred before and after the 2 earthquakes.Combined with the crustal deep structure in the area,the paper proposes that there will be proba bility of moderately strong earthquake in the middle and the south of Shanxi in future.
