Abstract

Abstract: This paper conducts a comparative analysis and discussion on the experimental result regararding the georesistivity anisotropic changes in the pressed rocks, and on variational characteristics of georesistivity anisotropy in strong earthquake preparation. The results show that the variational characteristics of georesistivity anisotropy during seismogenic process are as same as those of the pressed rocks, and they are also as same as the fracture development during rock rupture in mechanical experiment.

Key words: Georesistivity, Pressed rock, Anisotropy, Experiment study, On the spot observation
