摘要
The authors divide the north margin of Western Qingling Fault zone into six segments, namely, Baoji, Tianshui, Wushan, Zhangxian, Huangxianggou and Guomatan segment from east to west. The authors find that both the Huangxianggou and Zhangxian segments have the biggest probability of rupture in the future; and Tianshui segment is the second. If there will be a combined rupture, it is most likely to happen in Huangxianggou and Zhangxian segments, both of which have higher earthquake risk. The authors also compute b value along the fault zone. The image of b value indicates a high accumulated stress on the Huangxianggou and Tianshui segments. So the authors suppose that the two areas are the main locations where strong earthquakes may occur in the future.
