1739年银川-平罗8级地震灾害的历史辨析
|
摘要
在查阅了大量有关1739年银川-平罗8级大震历史资料的基础上,结合建国以来对银川平原地震的研究成果,研究了1739年银川-平罗8级地震的地震烈度分布及其灾害特点。研究认为:该地震的发震构造为贺兰山东麓断裂,而极震区位于其东南的银川-平罗一带,与银川地堑第四纪沉降中心相吻合,这主要是受到工程地质条件的影响。其震害特点对减轻未来地震灾害、城市规划等都有参考价值。
Based on consulting an ample historic data about Yinchuan-Pingluo M8 earthquake in1739 and combined with the former studies on some earthquakes in the Yinchuan Plain the distribution of the earthquake intensity and the characteristic of the earthquake disaster are researched. The result indicates that the earthquake was caused by the Helanshan fault in the the eastern piedmont of Helan Range, the most destroyed area lies its southeast area Yinchuan-Pingluo region, where is identical with the Quaternary sedimentation center of Yinchuan rift and affected mostly by the engineering geological conditions. The characteristic of this seismic disaster have important significance and active effects on the city layout and decreasing earthquake disaster in the future.
