摘要
震群是一种地震序列，在地震活动性问题研究中占有重要地位，具有特殊意义。文章讨论了三种震群：小震群、中强震群和强烈震群的地区分布特征及其前兆意义，并提供三种震群的世界分布图。
Earthquake swarm is a kind of seismic sequence It plays an important role in the research on seismicity and it has special significane This paper discusses three types of swarms,such as regional distribution characteristics of small swarms,moderately strong swarms and strong swarms,as well as their precursory implication The paper also provides a map for the worldwide distribution of the three kinds of swarms
