The GSJ is a virtual organization in The National Institute of Advanced Industrial Science and Technology (AIST), an Independent Administrative Institution (IAI) under the Ministry of Economy, Trade and Industry (METI) of the government of Japan. There are three research institutes (Institute of Geoscience, Institute for Geo-Resources and Environments, Marine Resources and Environment Laboratory) and two research centers (Research Center for Deep Geological Environments, Active Fault Research Center) in GSJ. Multidisciplinary scientific projects are organized by tapping the pools of professionals from each institute.
Principal activities at present are as follows :
1. Basic geological investigation of the country and surrounding marine areas.
2. Evaluation of energy and mineral resources and research related to their genesis.
3. Protection of the geological environment, and mitigation of geological hazards.
4. International scientific and technical cooperation in the fields of geology and mineral resources.
5. Development of fundamental techniques for earth science study.
6. Distribution and dissemination of earth science information.
STUDIES ON VOLCANOES:
A. Study on formation process and eruption mechanism of active volcano
1. Geological study on the active volcanoes with field survey, age determination, chemical analysis to make up the geological map of volcanoes.
2. Study of magma generation, differentiation, ascent and eruption processes based on geological, petrologial, geophysical and geochemical observations.
3. Assessment of volcanic activity with ground deformation, thermal or volcanic gas monitoring, and the urgent observation at the volcanic eruptions.
