It is not always adaptable for regions of landslide to use the resistivity method, because resistivities are often too low there to be measured. Our measurements have shown that the resistivity method is suitable for the place at Ikantai, although full measurements have not been carried out.
We have found three or four layers at every observation point. Loughly speaking, the resistivity of each layer is 10, 10, 1 and 10 ohm-meter in order from the surface of the ground. Geological surveys will be soon carried out. We wish to have full investigations after that time.
