| 摘 要： | Chengdu fault depression is an important Quaternary basin in the piedmont of Longmenshan mountain.Formation and evolution of the fault depression are entirely controlled by the Longmenshan piedmont fault and the Longquanshan fault.Since the late Quaternary,Chengdu fault depression has been subjected to an NW-SE oriented compression.Many NE or NNE trending faults inside the depression or near its margins show thrust slip,resulting in moderate and strong earthquakes along the piedmont Longmenshan fault,the western slop Longquanshan fault,and Pujiang-Xinjin-Chengdu-Deyang fault.It is indicated that three faults as mentioned above have the potential capability for the occurrence of moderate earthquakes.

| Abstract: | Chengdu fault depression is an important Quaternary basin in the piedmont of Longmenshan mountain.Formation and evolution of the fault depression are entirely controlled by the Longmenshan piedmont fault and the Longquanshan fault.Since the late Quaternary,Chengdu fault depression has been subjected to an NW-SE oriented compression.Many NE or NNE trending faults inside the depression or near its margins show thrust slip,resulting in moderate and strong earthquakes along the piedmont Longmenshan fault,the western slop Longquanshan fault,and Pujiang-Xinjin-Chengdu-Deyang fault.It is indicated that three faults as mentioned above have the potential capability for the occurrence of moderate earthquakes. |
