コンビーナ:馬場聖至(東京大学地震研究所)、後藤忠徳(兵庫県立大学大学院生命理学研究科)、内田利弘(産業技術総合研究所)、茂木透(東京工業大学理学院)

Detailed subsurface images by electric and electromagnetic (EM) surveys are indispensable to investigate the electrical features of the interior of the Earth both for academic and commercial purposes. The technologies, techniques, and methods for surveys, data analysis, and interpretation involve many common aspects that should be solved by scientists and engineers in cooperation since the studies cover a broad range of targets in various spatial-time scales and places on land and seafloor, e.g., natural resource explorations, environment and hazard evaluations, and the crustal and mantle tectonics and dynamics. And 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 and EM survey technologies and techniques including instrumentations, the data analysis methods including modeling, inversion, and imaging techniques, and the scientific achievements including novel way of interpretations, from the world.
