| 摘 要： | 列举陕西韩城地震台地倾斜资料对应汾渭地震带上的山西和陕西地区地震出现的震兆反应，表现在地倾斜矢量图有打折、打结和倾斜速率明显改变等异常。对于2008年5月12日四川汶川地震，地倾斜在震前一、二年出现矢量图变化速率明显改变的特征，认为属于震前异常。

| Abstract: | The precursor responses of the ground tiltmeters observation data at Hancheng to earthquakes of Fenwei seismic belt are enumerated in this paper.These responses exhibit anomalies of vector graph folding,knotting and obvious changes in tilted velocity of ground tiltmeters.The obvious velocity variation characteristics recorded by ground tiltmeters in one to two years before Wenchuan,Sichuan earthquake on the May 12th,2008 is believed to be the pre-earthquake anomalies. |
