| 摘 要： | 1998年1月10日张北6．2级地震前，怀来地震台SQ－70光记录倾斜仪出现了错位掉格现象，震后恢复。在分析倾斜资料信度的基础上对异常特征进一步探讨，倾斜异常特征主要是光记录曲线错位，错位频次与方向和孕震断层活动有密切的内在联系。本文对张北地震前怀来地震台倾斜异常特征进行分析，探讨地震台站利用异常资料预报地震的有效途径。

| Abstract: | the calibration of the SQ 70 Horizontal Pendulum Tiltmeter had dropped before Zhangbei M 6.2 earthquake in Jan. 10, 1998, and it recovered after the event.Based on the analysis to the confidence of the data the character of anomalies is discussed.The main character of ground tilt anomalies is the offset of the curve recorded with light,and the frequency of offset has closed relation with seismogenic faulting.In the paper,the character of ground tilt anomalies in Huailai Seismostation before Zhangbei earthquake is discussed,in order to find an effective way of earthquake prediction with ground tilt data. |
