| Abstract: | On the basis of the 3D velocity structure, the active tectonic blocks, the seismic activity, etc. in Yunnan area, a 3D finite element model is established. By determining the model’s boundary conditions based on the GPS data, the tectonic stress field in Yunnan area is simulated numerically. Through comparing the tectonic stress field with the M6 earthquake distribution in recent one hundred years, it is found that the stress transitional sections correspond well with the occured strong earthquake and three potential seismic risk regions are given. |

| Keywords: | Yunnan area tectonic stress field the maximum shear stress strong seismic activity seismic risk region |
