| Research Abstract |
Through this research project, the scientific achievements are as follows: (1) Development of a compact data acquisition system with multi channels and solar battery for in-situ landslide observation of self-potential, (2) Development of self-potential tomography and noise reduction to visualize underground water condition, and (3) Installation of a practical base at Nishi-Ikawa, Tokushima, Japan to monitor self-potential at an in-situ slope. These achievements provide the new findings on hydrological-geotechnical-electromagnetic coupling for landslide processes and accumulation of the in-situ observation data. And they have been reported in 10 scientific papers (4 papers with review) and 34 scientific presentations at international and domestic meetings.
