本文通过地震前深井电阻率的异常变化实例,试图说明震前在震源区附近及其较大范围内存在着深井电阻率的异常。通过精密观测(误差在1％以下),能获得地震的前兆信息。
In this paper, an example of abnormal changes of deep well resistivity before earthquakes is attempted to illustrate the existence of a deep well resistivity anomaly near the source region before the earthquake. By precision observation (error below 1%), the precursory information of the earthquake can be obtained.
