Abstract We simulate and calculate the spatial distribution and the time dependent characteristics of the induced geomagnetic under different depths, intensities and changes. In addition, the distortion current intensity and distribution depth before the Minxian-Zhangxian MS6.6 earthquake in 2013 are calculated based on the electrical structural results of magnetotelluric sounding in the southeast of Gansu province. The difference between the superposition effect on the Z component and the measured data is very small. The model explains the site of a large range low point displacement before the earthquake, and the method may also be used in other areas with low point displacement with clear electrical structure.
