Analyses of the induction vector and 2-D resistivity inversion along the NNE-SSW direction have been performed. The overall structure of this area is characterized by horizontally stratified resistivity of H-L-H-L from surface to depths. A distinct low-resistivity body lies beneath the Showa-Shinzan lava dome at 2-3 km deep, below which an isolated high-resistivity body has been estimated.北海道大学大学院理学研究院自然史科学部門(地球物理学)Departmental Bulletin Paperapplication/pdfhttp://hdl.handle.net/2115/38147info:doi/10.14943/gbhu.72.107https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/38147/3/07_Takakura.pdf0439-3503AN0008976X北海道大学地球物理学研究報告721071152009-03-15jpnpublisher
