| Abstract (English): |
We use the cross-fault deformation observation data of Jinzhou seismic station to analyze the current activity characteristics of Jinzhou fault. The long-term trend analysis results show that the Jinzhou fault is dominated by right-lateral and normal fault activities, and the overall activity level is relatively weak. The results of segmented analysis of fault activity show that the activity rate of northern section is higher than that of southern section. The GPS data shows that 2011-03-11 Mw 9. 1 earthquake in Japan had a mitigative effect on stress accumulation in northeast China. Combined with the analysis of cross-fault data of Jinzhou fault, we conclude that the annual fault activity rate has been significantly weakened in 2011-2014, and the fault activity has been consistent with its back-ground data since 2014, but the activity level is relatively weak.

利用金州地震台跨断层形变观测资料分析金州断裂现今活动特征。长趋势分析结果表明,金州断裂 以右旋兼正断为主,活动水平总体较弱。断裂活动分段分析结果表明,北段活动速率高于南段。GPS资料分 析表明,2011-03-11日本 MW9.1地震对东北地区应力积累具有缓解作用,结合金州断裂跨断层数据认为,金 州断裂在2011~2014年活动速率明显减弱,2014年至今断层活动与其背景资料一致,但活动水平较弱。 [ABSTRACT FROM AUTHOR] |
