The Obaku fault is an active fault bounding the south-eastern edge of the Kyoto Basin. The location and underground structure of the fault has been investigated by means of electric-resistivity survey (ρau method), borings and trench excavation. The findings are discussed by comparing existing information on the fault obtained by seismic surveys, observation of microtremors and γ-ray measurements with observation of outcrops made in a construction-work area near the investigated site. This study reveals that the electrical method is effective for detecting discontinuities at shallow depths, and also other geophysical methods have their merits at various stages of investigations of active faults.
