| Abstract: | Using net resource data sharing platform of earthquake profession, all observation data of precursory stations in ＂the tenth-five- year project＂ around before the 2010 Datong-Yanggao, Shanxi earthquake of M4. 5 are selected, and Observation data are dealed with and analyzed by using original imagine and multiterm method. The result indicates that only deformation data appears typical short and imminent anomaly, and that abnormal types not only have typical individual remarkable anomaly, but also have common anomaly which many stations have, and that abnormal station items all are located in north of Shanxi earthquake belt. |
