| Summary | The geological structure of the Chugoku and Shikoku regions of Japan is complex, and there is no overall model of the electrical resistivity structure of this region. In this study, we present horizontal distribution maps of magnetotelluric(MT) response functions (apparent resistivity and phase) calculated using Network-MT data, which were collected from Nippon Telegraph and Telephone Corporation telephone lines in this region during the period between 1994 and 1995. In comparison to traditional MT methods, the Network-MT method employs long dipoles for measuring electric fields, resulting in higher signal-to-noise ratios and eliminating static shift effects. The analysis of high-confidence data yielded interesting results of out-of-quadrant impedance phases at some sites. |
