Abstract

Abstract

Mongolia is an important neighbor of northern China. Western Mongolia ancient tectonic is a major structure in north of north-south tectonic earthquake zone, one important earthquake zone in China. In this paper, surfaces spline (SP) method is used to calculate the geomagnetic data on 119 sites in Mongolia on 2010.0 epoch, and the geomagnetic spatial structure in Mongolia is obtained. The results show that the geomagnetic spatial distribution of magnetic components given by SP model and EMM is similar, but there are some differences in part. These differences can reach ±30' for I, ± 60' for D and ± 500 nT for H, F, X, Y, Z.
