摘　　要：研究2013年1月29日哈萨克斯坦6.1级地震前新疆境内形变资料异常。结果表明:震前乌什水管仪两分量、伸缩仪北南分量、体应变和克孜尔水准、基线存在趋势性转折异常;乌什水管倾斜仪北南分量、体应变、分量式应变与柯坪垂直摆倾斜仪北南分量、拜城地倾斜两分量和库车东风煤矿地倾斜北南分量存在不同程度的中短期异常,趋势异常和中短期异常显著。In this paper,the deformation anomaly data of Xinjiang before Kazakhstan 6.1 earth-quake,which occurred on January 29,2013,is studied.The results indicate that the water tube tiltmeter data,the extensometer north-south component,the volumetric strain data of Wushi Seismic Station and Kizil standards,baseline emerged trend turning anomalies before the earthquake.The water tube tiltmeter north-south component,the volumetric strain data,the borehole Strainmeter data of Wushi Seismic Station,the vertical pendulum Tiltmeter north-south component in Keping,the ground inclinometer data in Baicheng and the ground inclinometer north-south component in Kuche emerged varying degrees of short-term anomalies.The proportion of trend anomaly and short-term anomaly is high.The paper also discussed the seismogenic background of Kazakhstan MS 6.1 earthquake.
