A DISCUSSION ON THE INTENSITY DISTRIBUTION CHARACTERISTICS OF 1626 LINGQIU EARTHQUAKE AND THE EARTHQUAKE - BLOCKING STRUCTURE
-
摘要: 对1626年灵丘地震的破坏情况进行了重新考证,着重指出了灵丘地震烈度沿唐河大断裂的高值异常和向西的快速衰减特征。在此基础上,提出了阻震构造的概念并进行了相应的理论分析。文章最后指出:唐河大断裂是1626年灵丘地震的阻震构造。Abstract: This paper made a reexamination on the damages of the 1626 Lingqiu earthquake and it is pointed out that the intensity of the Lingqiu earthquake showed a high-value anomaly along Tanghe great fault and a fast attenuation towards west.Based on this.the concept of earthquake-blocking structure has been put forward and the corresponding theory analysis has been made.Finally,it is pointed out that the Tanghe great fault is the earthquake-blocking structure of the 1626 Lingqiu earthquake.
