| Abstract: | Gaoling Ms4. 4 earthquake occurred on Nov. 5th, 2009 in Shaanxi province. Some short-term a- nomalies of deformation data appeared before one week in Shaanxi seismic stations. In this paper, the anomaly characteristics and focal mechanism are analyzed , the results show that： ① Anomaly amplitude is inversely proportional to epicentral distance ;② Abnormal of direction and stations distribution are consistent with the focal mechanism of the event. |
