摘　　要：本文总结了山东及其沿海地区Ｍ≥６级地震发生的地质构造背景，发现山东及其沿海地区强震活动很少发生在新构造单元内部，而是主要集中于新构造单元边界上，活动断裂对强震具明显的控震作用，不同活动时代、不同切割深度断裂，其控震能力不同，活动断裂交汇处是发生强震较多的地方。The tectonic conditions of strong earthquake with M≥6 in Shandong Province and its adjacent seas are summarized in this paper. The results show that most of strong earthquakes are concentrated along the margins of neotectonic units and few inner the neotectonic units. Occurrence and development of strong earthquakes are clearly under the control of active faults, which, however, are different with active ages and depths. The intersection areas of active faults are usually strong earthquake-prone areas.
