摘　　要：介绍了2013年1月29日哈萨克斯坦MS6.1地震基本参数、地震序列特征、震源机制解,分析地震前震源区周围的地震活动结果表明该地震序列是主余型、余震活动呈间隙式,衰减迅速,震源断错性质为走滑型。震前震源区存在4级地震围空、地震平静、中等地震增强和小震群等中短期异常。The paper introduced the basic parameters, seismic sequence characteristic, focal mechanism solution. The analysis of seismic activity around the epicenter showed that the seismic sequence is major-aftershock type, the aftershocks activated intervallic and attenuated quickly and the focal dislocation property is strikeslip type. There is midshort term anomaly such as seismic gap with Ms4.0, seismic quiescence, moderate earthquakes enhancement before Kazakhstan Ms6. 1 earthquake.
