摘要

以辽宁省长期丰富的地震前兆资料为基础,研究了内蒙两次5 9级地震与内蒙、东北地区前兆特征的关系。结果表明内蒙地震前前兆异常特征主要有:(1)前兆异常在时间上伴随内蒙巴林左旗5 9级地震事件的发生和结束呈阶段性起伏,空间上存在特征迁移;(2)中短期前兆异常阶段中以地形变为主体,在短临阶段地下流体和地磁出现异常。
On the basis of the much precursory information in Liaoning province,the relation between the two times M_S 5.9 earthquakes and the precusory characteristics in Neimeng and Northeast area was researched.The results showed that there are some precursory anomaly characteristics before the events:(1)precursory anomaly stage rising and falling on the time was accompanied by the occurence and termination of M_S5.9 earthquake,and it has the migration characteristics in the space; (2) the drformation anomaly was mainly observed in the mid-short term precursory anomaly stage,and the anomalies of the underground fluid and geomagnetism were observed in the short-imminent stage.
