One of the major components of Regional Hydrological Study Project is to build up a series of investigation technique to understand distribution and characteristic of major fault that influence ground water flow. We carried out High-Density Electrical Prospecting and Multi-Offset-VSP investigation as target for lineament at Tsunegara area in Mizunami city, and we studied the applicability of each method to detect a fault.
