中文摘要：

东昆仑断裂带是青藏高原东北部一条重要的断裂，具有明显的分段活动性。现代在不同段发生过多次由东向西迁移的强震，连接形成千余公里长的地表破裂带。各段历史地震调查、古地震、复发周期和滑动速率等研究表明东昆仑断裂带存在两个地震空区，其中玛曲段地震空区的危险性大，最大潜在地震矩震级不小于7．5。

英文摘要：

The eastern Kunlun fault zone is an important fracture in the northeast of Qinghai Tibet plateau, and it has obvious segment activity. Strong earthquakes have occured several times by the westward migration and formed more than 1 000 km long surface rupture zone. According to history seismic survey, ancient earthquake and recurrence intervals and sliding rate studies in different segments, it is found that the eastern Kunlun fault zone has two seismic gaps, the Maqu segment is the most dangerous one, and the maximum potential moment magnitude is not less than 7.5.
