Based on aeromagnetic data, the characteristics of the magnetic structures and its relationship with seismicities in the North-South Seismic Belt are discussed in detail in this paper. It can be derived, from the analysis of the magnetic structure layers,that the shallow NW and NE structures show mainly a network compounding of the structures striking, whereas the deep structures striking NS and EW perpendicular intersction. The regional seismicities, particularly the scale and strength, indicate a close relation to such structural environments.
