| 摘 要： | 安丘-莒县断裂是沂沭断裂带最主要的活动断裂,对强震的发生具有明显的控制作用。该断裂的安丘—朱里段由南流段、双官—眉村段和朱里段3条右阶斜列的次级断裂所组成,以右旋走滑活动为主,兼有正断或逆冲活动分量;其最新活动时代推断为晚更新世—全新世早期。根据断裂活动性的最新研究成果,认为在莒县至昌邑之间安丘-莒县断裂仍是占主导地位的活动断裂,与公元前70年安丘7级地震的发生具有密切关系

| Abstract: | The Yishu Fault zone is a part of the Tanlu Fault zone that passes through Shandong Province and the northern area of Jiangsu. It is composed of 5 nearly parallel faults among which the Anqiu-Juxian Fault is the most important and prominent active fault since late Pleistocene and is usually considered to be the seismogenic fault of the 70 BC M 7 Anqiu earthquake and the 1668 AD M 8~1/_2 Tancheng earthquake. By detailed research in recent years, e.g. the active fault mapping implemented during the “Eighth Fi |
