摘要
对2003年新疆巴楚—伽师6.8级地震序列进行了初步分析,结果表明其余震具有共轭型分布特征;多种地震学参数在序列中的较大余震前有不同程度异常显示,余震具有较为特殊的地震波形;与1997—1998年伽师强震群相比具有多处异同点等。结果认为巴楚—伽师6.8级地震可能为具有继承伽师地震特点的余震起伏变化较大的主余震型。
Bachu-Jiashi region of Xinjiang occurred M6.8 earthquake in 2003, this is the tenth M≥6.0 earthquake follow jiashi region from 1997 to 1998. preliminary analysis on M6.8 earthquake sequence show, after-earthquakes distribution have conjugate characteristic. Some seismic parameters show abnormities before the bigger after-earthquake in sequence, after-earthquakes have especial seismic wave. There have some difference and so on. when contrast Jiashi strong earthquake cluster from 1997 to 1998. The result show Bachu-Jiashi M6.8 earthquake sequence is major aftershock, and it can inherit Jiashi earthquake sequence characteristic, but its after-earthquakes change is big.
