We made audiomagnetotelluric sounding to image the subsurface structure across the Atera fault, which is a 66 km long active strike-slip fault in central Japan. A major feature of the resistivity model is existence of two dipping conductors at 0.5-2.0 km depth: one dipping southwest and the other northeast. These imply fractured zones, created either by strike slip movements or by vertical ones. An audiomagnetotelluric imaging is suited for mapping subsurface fractures zones in active fault regions.
