Scope 
Detailed and accurate subsurface images by electric, magnetic and electromagnetic (EM) surveys are indispensable for investigating the Earth's interior for both academic and commercial purposes. Technologies and techniques for data acquisition, analysis, and interpretation involve many common aspects that should be solved by scientists and engineers in cooperation because the studies cover a broad range of targets in various spatial-temporal scales and places on land and seafloor; e.g., natural resource exploration, environment and geohazard evaluation, and crustal and mantle tectonics and dynamics. In addition, the knowledge should be shared in the international community for further development of this field. The session invites papers on recent advances in the electric, magnetic, and EM survey technologies including instrumentation, data processing, modeling, inversion and imaging, as well as scientific achievements including novel ways of interpretation. The session is partially associated with activities of the Study of Earth's Deep Interior, Japan (SEDI-J).
