摘要: 本文提出了一种检验异常地震活动的统计方法, 并应用此方法研究了我国西部地区某些强震及中强震(Ms>5.0)前后的异常地震活动, 探讨了异常地震活动的某些基本特征.Abstract: In this paper a statistical method of detecting unusual seismic activities has been developed. The method proposed is then applied to weak earthquake activities before and after some strong and moderate earthquakes (Ms>5.0) in Western China. Certain fundamental characteristics of the unusual seismic activities have been investigated and discussed.
