Correlation analysis on co-seismic response between well water level and temperature caused by the Nepal MS8.1 earthquake

  • 摘要: 尼泊尔MS8.1地震引起中国大陆大量地震观测井水位和水温的同震响应. 从宏观结果看, 在54个同时存在水位和水温同震效应的观测井中, 有51口观测井的变化类型为水位上升-水温上升、 水位下降-水温下降、 水位振荡-水温上升或下降(以下降为主), 井水位与井水温同震效应表现出良好的相关性, 这可能与地下水动力学作用有关; 有3口观测井的水位变化与水温变化方向相反, 且水温变化均为震后效应. 另外, 有1口观测井水位无变化而水温同震效应明显. 这些不同类型的同震变化与井孔条件、 水温梯度、 传感器位置及水位埋深等多种因素有关. 从微观结果看, 井水位同震效应出现的时间及变化幅度与井水温同震效应出现的时间及变化幅度之间的关联性比较复杂, 这与井孔条件和温度梯度等因素有关.
    Abstract: It were recorded that a large number of co-seismic responses of well water level and temperature in Chinese mainland caused by the Nepal MS8.1 earthquake. There is good correlation between well water level and water temperature for 51 observation wells, which appears as water level rise to water temperature rise, water level drop to water temperature drop or water level oscillation to water temperature rise/drop (most of the co-seismic water tempe-ratures drop). The good correlation is resulted from the groundwater dynamics. As for three observation wells, the change in water level is in the opposite direction to the change in water temperature, which is the post-seismic effect. Meanwhile, one observation well has only water temperature co-seismic change but no water level change, which may have great relation to the borehole condition, water temperature gradient, sensor position and water level depth. The results also show that there is complex relationship between the initial time and amplitude of groundwater level change and those of groundwater temperature change, which is affected by borehole condition and temperature gradient.
