摘要
利用长趋势异常、矢量曲线、γ因子等方法对泰安、郯城、徐州3个台的7套倾斜仪进行了异常识别,得出泰安SQ—70石英倾斜仪、徐州SQ—70石英倾斜仪反映了山东苍山5.2级地震异常信息的结论。
The identification for the anomalies of 7 tiltmeters of 3 stations in Taian,Tancheng and Xuzhou has been made by the methods of the Long term tendency anomaly,the vector curve and ther factor,the conclusions that the SQ 70 quartz tiltmeters in Taian and Xuzhou station showed the anomalous informations of deformation have been obtained.
