The Japanese islands are located in the tectonically active Circum-Pacific Mobile Belt. As
a result, 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
2006, 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, existing information maintenance for researchof an activity history and distribution of an active fault (movement, extension, a development
process of a deformation zone) will be carried out. For volcanological and geothermal studies,
we are planning to extract a technique for detecting crustal magma and/or geothermal fluidin 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, making of concept model for landform
development will be carried out. Concerning a natural analog study, development of future
study schedule will be carried out. In addition, maintenance of development of analyticalmethods to perform the data acquisition that is necessary for these studies will be carried out.
In addition, this plan was made based on “Tono Geoscientific Research Unit quality
assurance rule research task control manual (October, 2005)” at the first half of 2006. About
the findings that we carried out based on this plan, we are going to report it by JAEA
Reports (JAEA-Research) which Japan Atomic Energy Agency publishes as “Annual Reportfor Research on Long-Term Stability of the Geological Environment in FY2006” after this.
