【Abstract】 In this paper, the operation status of geoelectric field observation system at Yushu Seismic Station is introduced in detail and the comprehensive evaluation from the aspect of data integrity rate, morphological changes, static disturbed days and correlation coeffi cient, interpolation on the observation system. The results show that observation system of geoelectric fi eld at Yushu Seismic Station runs stable and reliable, and is able to record abnormal changes of geolectric fi eld before the earthquake, can provide the basis for earthquake prediction study.更多还原
