ACHIEVEMENTS APPLICATION AND RECONSTRUCTION OF THE GEOMAGNETIC OBSERVATION NETWORK OF GEOPHYSICAL FIELD IN LIAONING |

| Abstract: | This paper resumed the reconstruction of the geomagnetic network at the geophysical field in Liaoning. Based on the observation data after reconstruction, the gradient distribution and the total geomagnetic intensity isoline distribution trend map are drawn. The gradient distribution law of the geomagnetic network after reconstruction has been discussed. The annual variation and the adjacent variation features of the important active faults and the old seismic zone in Liaoning are analyzed, which could provide support for the seismic prediction. |
