2016年11月25日阿克陶M_S6.7地震前,喀什台栏杆乡地磁、塔什库尔干60泉浅层水温、乌帕尔岩石地温资料均出现异常。前兆异常特征为:(1)喀什台栏杆乡地磁Z分量日变幅加卸载响应比出现2次超阈值情况;(2)塔什库尔干60泉浅层水温2016年9月17日温度快速阶升0.316℃变化;(3)喀什乌帕尔乡岩石地温20.65 m、23.06 m测项观测数据均出现较大幅度变化。
Before the Mk 6.7 earthquake in Akstao on November 25, 2016, the geomagnetic data of Tailan Township, Kashgar, the shallow water temperature of the Taxkorgan 60 spring, and the geothermal data of the Wupal rock all showed anomalies. The characteristics of precursory anomalies are as follows: (1) The daily amplitude of loading and unloading response of geomagnetic Z component in the railings of Kashi Taihtan Township appears twice exceed the threshold value; (2) The shallow water temperature of Taxkorgan 60 springs rapidly rises 0.316 ℃ on September 17, 2016 (3) The geothermal data of 20.65 m and 23.06 m in Wupaer Township, Kashgar, all showed significant changes.
