对１９８９ 年１０月１８日大同—阳高６．１ 级震群表现出的多种宏观前兆异常现象进行了调查与研究，叙述了大同—阳高地震前宏观前兆异常的主要表现形式，分析了这些宏观前兆异常出现的时、空、强分布规律及其与地震的关系，得出此次地震宏观前兆异常主要表现为突发性，宏观前兆异常空间分布的集中程度与烈度成正比，异常的空间展布方向与地震活动构造相关的结论。
This paper investigates and studies various macroscopic anomalous precursors of Datong-Yanggao M6.1 earthquake swarm on October 18, 1989, and narrates the main manifestations of macro-anomalous precursory anomalies before the Datong-Yanggao earthquake. These macroscopic precursory anomalies appear when the time and space, strong distribution and its relationship with the earthquake, concluded that the macroeconomic precursory anomalies of the earthquake mainly for the sudden, the macro-anomalous spatial distribution of concentration is proportional to intensity and anomalies The spatial distribution direction is related to the seismic activity.
