摘要
2015年7月3日新疆皮山县发生M_S6.5地震,震前塔什库尔干新60泉水温出现异常变化,以中短期异常为主,表现为泉水温度的下降—持续—上升的中期异常及临震前的快速阶升阶降变化,震后泉水温度缓慢恢复至背景水平。结合传统的P波初动法计算塔什库尔干台的小震平均震源机制解,对塔什库尔干台附近应力场变化进行分析,为塔什库尔干新60泉异常变化提供应力依据,同时对本次异常变化及机理进行浅析,为今后泉水水温异常判定提供参考。
PiShan earthquake with Ms 6.5 occurred on July 3rd, 2015. Taxkorgan new 60 spring wa- ter temperature presented abnormal change before the earthquake, and was given priority to short to medium term anomalies, which mainly showed down-last-up anomaly, then backed to background lev- el slowly. Combined with traditional P wave initial motion method to calculate average focal mecha- nism solution of small earthquakes of Taxkorgan ride,it analyzed the stress field change near Taxkor- gan station, provided the basis of stress for Taxkorgan new 60 spring changes. At the same time, a- nomalies and it＇ s mechanism were analyzed, which provided reference for the springs water tempera- ture anomaly judgement in the future.
