摘要
分析讨论了1991年1月13日发生在内蒙古阿拉善左旗5.2级地震前的地震活动时空分布与某些前兆异常特征,以及地震活动性和前兆观测的中期与临震异常的相互关系,并对该地区三次中强地震前地震活动性的差异进行了总结。
The characteristics of precursory anomalous situations and time-space distribution before the earthquake on Jan. 13,1991 has been analyzed and summarized. The effect and association between the seismicity and precursory observational anomalies have been approached also. Meanwhile, the difference of seismic activity in this region before three moderate strong earthquakes has been discussed.
