【摘要】 小震群地震活动经常发生,对其可能类型的快速判别,即对正在活动的小震群,究竟是"大震"的前震序列,还是并不伴有大震发生的一般性小震群的快速判别,对减轻地震灾害和维护社会稳定具有重要的现实意义。本文总结归纳了小震群序列类型判别方法研究的现状和存在的问题,并对震群序列类型判别研究的趋势进行了初步阐述。更多还原

【Abstract】 Small earthquake swarms often occur,and discriminating a foreshock sequence from ordinary small earthquake swarms quickly is very important both in the hazard mitigation and social stability.This article summarizes the current research situation in judging the type of small earthquake swarm,its existing problems are analyzed.Finally,some research trends in judging the type of an earthquake swarm have been elaborated.更多还原
