摘要

///Using depth-dependent layers and considering the subduction angle the Pacific Plate to Northeast China, the authors build a vertical static 2D finite element model about the Pacific Plate diving into Northeast China with subduction velocity of the Pacific Plate. By altering subducting angle, the authors discuss numerically the possible subducting process and its effects on deep and shallow earthquake. The results of the models show the stress distribution of the whole research region including total characteristic feature and region characteristic, and the active faults and its adjacent areas response to the stress from deep region. The research results imply that the subduction angle of the Pacific Plate and the environment around faults in the crust having great effects on deep and shallow earthquake activities.
