| Abstract: | The quality of the observed data of geoelectric field from Jiayuguan station is analyzed and appraised in six aspects,and the basic factors of geoelectric field change are discussed.The result shows that the data of Jiayuguan station have reflected the real change of earth electric field,and the records are accurate.The short-term and imminent precursors in the geoelectric field and telluric data before 4 times moderate and strong earthquakes occurred near Jiayuguan station are studied.It is considered that before moderate-strong earthquake there are some short and imminent anomalies in the geoelectric field data. |
