【摘要】 通过对研究区主要活动断裂最新活动段的重新划分，结合人工地震测深提供的深部壳幔结构特征，地震活动空间分布，重力测量、形变测量等资料，划分出三个中强地震危险区：宁城－新地区（５．５～６级）；朝阳－贝子府区（５．５～６级）和义县－柴都台区（５～５．５级）。认为未来３０年内，有可能发生中强地震的地区为宁城－新地和朝阳－贝子府区。更多还原

【Abstract】 By re divided recently active segment of main active fault in the research area,having combine crust and mantle structure by seismic sounding with man made source,seismicity space distribution,gravity repetition measurement,short range leveling etc.in this paper,the area is divide into 3 moderate strong earthquake risk regions that are Ningcheng Xindi region( M s5 5 6 0),Chaoyang Beizifu region( M s5 5 6 0) and Yixian Zidutai region( M s5 0 5 5) The authors suggest that the Ningcheng Xindi region and Chaoyang Beizifu region will occur moderate strong earthquake probably in the near 30 year更多还原
