Scope
|
The extremely large geomagnetically induced current (GIC) which possibly causes serious disasters to our society has not been supposed to occur in low-latitude countries like Japan. This groundless assumption has prevented active researches about the GICs in Japan. It is noted that the disaster possibly caused by the extremely large GIC will be catastrophic to our society. Therefore, we had the first scientific session about this issue in the last JpGU assembly. It was the epoch-making event that the space scientists including solar physicists and the solid-Earth geophysicists discussed the common issue together. As outputs of this session, we recognized the following problems to be settled for the GIC research in Japan, 1) estimations of intensity of the extremely large space weather event and the occurrence frequency, 2) propagation of extremely large solar wind disturbances from Sun to Earth and its impact to the geospace, 3) modeling of the GIC with a realistic ground conductivity distribution. Research papers about these problems will be published in the special issue of Earth, Planets and Space.
In the session this year, we will discuss the recent progresses about the GIC research stimulated by the last GIC session as well as the new topics including the magnetotelluric sounding based on a source field with finite spatial structure in the magnetosphere/ionosphere, recent modeling researches, and the new observation plans. We welcome related scientific and technical researches.
