[SSS31-P13] Geophysical explorations along the Gomura and the Yamada fault zone, and its applicability: Part 2 P-wave seismic reflection survey, seismic refraction survey, CSAMT survey, and gravity survey
Keywords:P-wave seismic reflection survey, seismic refraction survey, CSAMT survey, gravity survey, Gomura fault zone, Yamada fault zone
As a part of a research project commissioned by Secretariat of Nuclear Regulation Authority (S/NRA/R), to reveal the subsurface geometry of active fault and geological structure around the Gomura fault zone and the Yamada fault zone, we execute a seismic reflection and refraction survey, S-wave shallow seismic reflection survey, CSAMT survey, high-density electrical resistivity survey, and gravity survey. In this presentation, we demonstrate detail results of P-wave seismic reflection survey, seismic refraction survey, CSAMT survey, and gravity survey. Finally, we summarize applicability and efficiency of these geophysical explorations for the strike-slip active fault.
