北京地震台白家疃2#井不同层位水温观测数据对比分析

Comparative analysis on the water temperature data from Baijiatuan 2# well at Beijing Seismic Station

在地震前兆异常方面做了一些初步的分析,认为比起单口井观测单一层面上的水温更能捕捉地震引起的前兆信息。在有条件的井孔中,应该进行多点多层位的水温观测,这样能充分利用现有井孔资源更好的观测地震引起变化。

The comparative analysis on micro dynamic variation of water temperature observed by two thermometers at different layers of Baijiatuan 2@ well is carried out to find the reasons that cause the different variation shapes of water temperature at different layers. The primary analysis on the precursory anomalies shows that comparing with the water temperature observing at single layer of single well, the observation at multiple points and multiple layers can capture more clear precursors of earthquakes. It also shows that if the condition permits, the water temperature observation should be performed at multiple points and multiple layers to make better use of existing well resource for observing the precursory information caused by earthquakes.
