目前,在地震预报中,对地下水电导的测定已广泛应用于群专台站.几年来我测报点水化学分析的实践证明,在地震的孕震期里,尤其在临震前夕,由于震中应力场的急剧变化,引起了地壳形变,而伴随这一现象所引起的地下水动态变化使地下水的温度及各种离子浓度发生了异常变化.这些与地震信息相关的变化,可以测到地震的前兆信息.这为综合分析地震前兆提供了参考数据.
At present, in the earthquake prediction, the determination of groundwater conductance has been widely applied to the group of stations.In recent years, I measured the point of water chemical analysis of the practice proved that during the earthquake seismogenic period, especially on the eve of the quake, due to epicenter stress The dramatic changes in the field caused the deformation of the crust, and the dynamic changes of groundwater caused by this phenomenon caused anomalous changes in groundwater temperature and various ion concentrations. These changes related to the seismic information can be used to detect precursory information of the earthquake This provides reference data for comprehensive analysis of earthquake precursors.
