Upheaval phenomenon at the tip part of landslide is not so rare. But the upheaval at the opposite side of the river which runs at the tip part of landslide seems to suggest the factor of cause of the landslide. Accordingly, for the purpose of making clear the phenomenon, the study was carried out. In beginning, the electric survey was carried out at some landslide areas which had the specific upheaval phenomenon. As the result of the investigation, the next facts were revealed: (1) In some cases, the difference of the apparent resistivity between the upheaval area and the non upheaval area was caused by the occurence time of the upheaval phenomenon. (2) In other cases, the difference of the apparent resistivity between the upheaval area and the non upheaval area was caused by the geological factor.
