Abstract:: Based on 6 periods of mobile geomagnetic vector measurement from 2016 to 2021 in Hebei and its surrounding areas,this paper builds a model to illustrate the variation of the lithospheric magnetic field 4 years,3 years,2 years and 1 year before the July 12,2020 Tangshan M_S5.1 earthquake,and 1 year after the earthquake.The temporal and spatial evolution of the total strength,the magnetic declination,the magnetic inclination and the horizontal vector of the lithospheric magnetic field in the study area are compared and analyzed.The results show that:①The 4-year and 3-year cumulative variation of the 4 elements of the lithospheric magnetic field before the Tangshan M_S5.1 earthquake showed a significant trend in total in the region,which had a certain correlation with the geotectonic settings.Two-year and 1-year variation of the 4 elements of the lithospheric magnetic field before the Tangshan M_S5.1 earthquake showed significant characteristics in some parts of the study area.Four years,3 years,2 years,and 1 year before the Tangshan M_S5.1 earthquake,the variation of the total strength,the magnetic declination,and the magnetic inclination near the epicenter of the earthquake is insignificant,and most of the values distributed along the zero-value line.The horizontal vector showed continuous and weak variation.After the Tangshan M_S5.1 earthquake,the magnetic declination near the epicenter varied obviously,and so did the horizontal vector.②The temporal and spatial evolution of the lithospheric magnetic field variation before the earthquake showed that when approaching the original time of the Tangshan M_S5.1 earthquake,the trend of the spatial distribution of the local positive and negative variation would replace the overall variation trend in the region.
