A PHYSICAL EXPLANATION ON STAGE VARIATION OF EARTH RESISTIVITY TO EATHQUAKE

Chen Youfa ( Lanzhou Seismological Institute, Stste Seismological Bureau )  
In this paper, stage variation of earth resistivity to earthquakes is divided into six interval: 1.normal changes of earth resistivity during a seismic period; 2. trend of decrease in early period; 3. gentle changes of middle term before; 4. rapid short-term descent ; 5. sudden changes of rising again just before event ( i.e. occurrence of earthquake); 6, normal readjustment after event. The stage variation of earth resistivity to earthquake is explained on the basis of the view point of rock voids changes on the spot which are closure, reducing voids, then expasion, recovery and water saturation.
