| Abstract: | 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 |
