[SVC41-P05] Subsurface Resistivity Imaging by TDEM Method in Nasudake volcano
Keywords:Nasudake, volcano, Resistivity
On the western side from Minenocyaya-ato of the east-west survey line, it is shown that resistivity structure has a two-layer structure of low- medium resistivity, whereas on the east side it was a three layer structure with low- medium- high resistivity. The low resistivity value layer on the eastern side of the survey line is considered to indicate the fluidized layer of hot water because the source of the hot spring is dotted in the surrounding area.
On the north - south survey line, the resistivity structure was roughly a two - layer structure with low - medium resistivity.In the fumarolic area, the layer thickness of low resistivity was thin, and the medium resistivity area continued until the analysis depth (altitude 800 m).
