Abstract

 The Society of Exploration Geophysicists Japan (SEGJ) was established in 1948. SEGJ has reached its 65th anniversary in this year. Research and development as for exploration geophysics have been performed to support various social needs until now. We can now handle enormous data by adopting advanced electronics and computer technology. As a result, three-dimensional and four-dimensional explorations have been enabled.<br>  The Japanese energy policy is standing at a turning point since the East Japan Earthquake disasters. On the other hand, our expectation increases for new mineral and energy resources such as methane hydrate and rare earth elements. However, the uneasiness to security by the deterioration is actualized such as the ceiling collapse accident in the Sasago Tunnel when we turn interest to social infrastructural facilities. Natural disasters diversify from deep-seated slope failures, landslides to abnormal weather events in recent years. Furthermore it is concerned about the Nankai Trough mega earthquake or the directly Tokyo area earthquake.<br>  We performed the panel discussion by four researchers or engineers to study about how we can contribute using exploration geophysics in such complicated situation surrounding Japan. We discussed the prospects in the future of SEGJ which reaches the 75th anniversary ten years later. The topics were offered from the four panelists on the viewing points of innovation, social needs, personnel training and sustainable society. Active discussion was accomplished from the audience. We discussed about the following suggestions ; social needs are opportunities of the innovation ; clear explanation about the applicability of the geophysical exploration is necessary on the viewpoint of the users ; we must find engineers from overall natural science widely without limiting to geoscience ; it is important to visualize subsurface using the continuous monitoring.<br>
