| Abstract: | This paper presents results of Curie Boundary, Moho, isostatic gravity anomaly and stress field caused by flow in mantle, using gravimetric- magnetic data obtained in and around Shanghai area. And methods of calcu- lation are also given. Based on the preliminary analysis of the results, deep- seated geological structure feature and its relation with seismic active trend are described. Curie Boundary and its relation with seismic activity are dis- cussed. Finally, some opinions about seismic active trend are given. |
