| Abstract: | In order to image the 3-D velocity structure of its shallow crust in Kunming region,China,finite-difference seis-mic tomography is used to invert the seismic data selected carefully from six-shot data. The result lays a founda-tion for the discussion of the relationship between the obtained velocity structure and the hidden faults,and for the illumination of the depth extents of main active faults surrounding Kunming city. Puduhe-Xishan fault lies on the western margin of the Kunming basin and is just situa... |
