摘要: 本文通过特征地震特点与枢纽运动特征的对比分析,得出走滑断裂的枢纽运动是形成特征地震的一种机制,断裂的枢纽轴部是特征地震发生的位置。研究结果表明,富蕴、海原、炉霍和郯城地震断裂皆属特征地震断裂。

Abstract: Based on the analysis and comparison of the features of characteristic earthquake and pivotal movement,it is concluded that the pivotal movement of strike-slip fault leads to the occurence of characteristic earthquake,and that the pivotal axis of the fault is the site of earthquake occurence.The result also shows that the Fuyun,Luhuo,Haiyuan and Tancheng faults are the seismogenic faults of characterstic earthquake.

Key words: Strike-slip fault, Pivotal movement, Pivotal axis, Characteristic earthquake
