| 摘 要： | 对北天山地区2016年12月8日呼图壁MS6.2地震周边300 km范围内跨断层精密水准资料进行分析,运用二倍均方差对异常进行判定,计算出2012~2016年断层的趋势累积率Dc,认为地震前存在着一定范围的应力积累、加速运动、尖点突跳等中短期前兆异常,地震发生在形变异常显著及断层形变趋势累积率高值区域。

| 关 键 词： | 呼图壁MS6.2地震 形变 跨断层 趋势累积率 |

| Abstract: | Based on analysis of the precise leveling data across faults within 300 km around Hutubi MS6.2 earthquake on December 8 th,2016 in the Northern Tianshan area,the double mean square deviation is used to judge the anomalies,and the trend accumulation rate DC of faults in 2012~2016 is calculated.It is considered that there are some short and medium-term precursory anomalies such as stress accumulation,acceleration movement and sharp point jump before the earthquake.The earthquake occurred in the area with significant deformation anomaly and high accumulation rate of fault deformation trend. |

| Keywords: | Hutubi MS6 2 earthquake Deformation Cross fault Trend accumulation rate |
