The Japanese islands are located in the tectonically active Circum-Pacific Mobile Belt. As aresult, Japan has a high frequency of earthquakes and eruptions. The concept of geologicaldisposal of HLW in Japan is based on a multi-barrier system which combines a stablegeological environment with an engineered barrier system. Therefore, special consideration
is given to the long-term stability of the geological environment, taking into accountvolcanism, faulting, uplift, denudation, climatic change and sea-level change in Japan.
Development of research/prediction technologies for geotectonic events has been carried out
to evaluate the long-term stability of the geological environment in Japan. During fiscal year
2007, to confirm existence of the phenomena that have a influence on geological disposal
system (e.g. active fault or magma), to confirm that there was not the trace that thephenomena occurred in the past, to predict/evaluate possibility of the phenomena and todevelop the research/prediction techniques about the following items will be carried out.
Concerning active fault and seismic activity, case study for research of an activity history anddistribution of an active fault (movement, extension, a development process of a deformationzone) will be carried out. For volcanological and geothermal studies, we are planning toprovide an integrated approach for detecting crustal magma and/or geothermal fluid in deep
underground using geophysical and geochemical data, and models assessing the likelihood of
future volcanism and its influence on geological environment. Concerning uplift, denudation,
climatic change and sea-level change, development of techniques that researches
paleo-topography and paleo-environment and that simulates of landforms will be carried out.
Concerning a natural analog study, information maintenance about a change of geologicalenvironment with hydrothermal activity will be carried out. In addition, maintenance ofdevelopment of analytical methods to perform the data acquisition that is necessary for thesestudies will be carried out.
