| 摘 要： | 1879年甘肃武都南 8级地震发震断裂的确认是一个未决的问题。文中通过卫星影像解译、史料记载分析,认为沿文县东北水坑山北麓NEE向的范家坝 -临江断裂可能分布有该次地震的地表破裂带,因而,这一条断裂可能是该次地震的发震断裂。由此,可在发震断裂的产状变化、活动方式、地表破裂带长度、水平位错量大小及沿断裂的分布、断裂的区域归属、宏观震中位置、可能震级大小、震害分布等诸多方面取得一致

| Abstract: | The earthquake occurred in Jiezhou, Gansu Province on July 1, 1879 (May 12, Guangxu 5, Qing Dynasty) is one of the largest earthquake events in Chinese history. The effect of this event spread over more than ten provinces. According to historical data, the magnitude of this earthquake has been estimated to be 8 or 71/2, and the macroscopic epicenter has been located at Mianshanheba (104.7E, 33.2N), south of Wudu, Gansu Province, with type II precision of estimation (≤25km error). As the earthquake occurred |
