Electric-seismic effects in liquid saturated friable-linked mediums.

The series of experiments on research of electric-seismic effects have been carried out in the<br>laboratory physical models of liquid saturated friable-linked media under atmosphere pressure. As a physical<br>model there was used the one-dimensional sand model saturated with different conductance liquids. The<br>seismic parameters of longitudinal and shear waves in acoustical frequency range of 250Hz-5kHz have been<br>studied under influence of external direct electric current of different value. The significant changes of<br>seismic amplitudes and velocities as well as amplitude spectra were observed depending on quantity of<br>electricity passing through the medium saturated by the conductance liquid. At the same time there were no<br>considerable changes of seismic parameters in the case of medium saturated with non-conductance liquid. A<br>possible mechanism of these effects is discussed.
