摘要
The radial flow of fracture water in faults is comparatively concentrated and can be regarded as a kinetic conductor.The obvious dynamic responses are formed in faint natural electromagnetic field by the flowing groundwater.Its unstable flowing will bring complicated and time-dependent electromagnetic induction on time and space.These dynamic responses are not only related with its depth and hydraulic gradient,but also closely related with observation frequency.
