用震中迁移交会讨论1668年郯城81/2级地震——纪念郯城大震350周年

Discussion on the Tancheng M8 1/2 Earthquake of 1668 Based on the Intersection of Epicenter Migration: For the 350th Anniversary of Tancheng Earthquake

摘要:

1668年郯城8¹/₂级地震，其极震区的位置是符合4³/₄~5¹/₂地震构成的震中迁移交会的。由震中迁移交会寻找该大震震源比由空区寻找该大震震源的地理范围要更具体一些。另外，该文也附带讨论了1668年郯城大震特强的原因。

Abstract:

The location of the meizoseismal area of the Tancheng M8 ¹/₂ earthquake in 1668 corresponds with the result based on the intersection of epicenter migration of earthquakes with a magnitude of 4³/₄~5¹/₂. It is easier to find the geographic range of the M8 ¹/₂ earthquake source using the intersection of epicenter migration. Moreover, the reason for the Tancheng earthquake's high magnitude is discussed in this study.
