摘要
对本台地磁低点位移异常与1988年以来祁连山西段ML≥5 0级地震相对应的震例进行了分析研究,并讨论了2003年4月17日青海德令哈6 6级地震前本台断层气氡资料的异常变化。结果表明,该地区的地震活动和地磁低点位移异常都与其构造活动有着密切的联系。
The relation between the anomaly of geomagnetic low-point displacement at Jiayuguan station and the earthquakes with Ms≥5.0 since 1988 in west segment of Qilian Mountain fault is analyzed, and the anomaly of the fault gas radon before Delingha earthquake with Ms66 on Apr172003 is discussed, the results show that the seismicity and geomagnetic low-point displacement have a close relation to the structural activity.
