| Abstract: | Geomagnetic observation is one of the most important precursor methods of earthquake prediction. It is particularly important to identify and remove the interference in order to ensure reliable data. According to problems occurred in the observation of nuclear precession magnetometer in Jingxian Seismic Station, we analyze on the data using contrast observation method. The results showed that the equipment is high accuracy and stable. And we also pointed out that some issues should be paid attention. In addition, the magnetic interference source in the geomagnetic observation of our station has been eliminated. |
