| 抄録: | From continuous observations of earth currents during a magnetic storm at two sites onthe Atotsugawa Fault, Nishiamo (NAM) and Miyagawa (MYG), and also from geomagneticvariations observed at the Kakioka station, the direction of the maximum change of electricself-potential has been determined by using the magneto-telluric (M.T) method.The maximum direction (M.D) was found to be E105N, which is nearly orthogonalto the strike of the fault, and the amplitude of the geoelectric variations at NAM was abouteight times as large as that at MYG.These observed results suggest that there exists a layer of high resistivity beneath theNAM station.From the geomagnetic and geoelectric observations the wave impedance, E/H has beendetermined as a function of frequency and the apparent resistivity in the vicinity of thefault has been estimated. |
