Resistivity is sensitive especially to existence of interstitial fulids and their connectivity. Electromagnetic observations reveal subsurface conditions such as stress, temperature and fluid motion through piezomagnetic, thermal magnetic and electrokinetic phenomena. Then, while performing and promoting cooperative field experiments for resistivity structure determination and electromagnetic field monitoring, we try to elucidate the physical process which can be extracted from the observations. We are also developing new techniques of field experiments, data processing methods and 3-D resistivity inversion.
