Study on collection and arrangement of geoscientific information on upgrading of impacts assessment model for seismic and fault activities on a HLW geological disposal

Kawamura, Makoto

To evaluate the hydraulic and mechanical effects associated with seismic and fault activities, a "conceptual model of seismic and fault activities" has been constructed. However, this conceptual model is qualitative with emphasis on versatility and general viewpoints, and numerical data referred to when setting parameters relating to numerical analysis has not been arranged. In this study, we collected and arranged information published by research institutions such as the Japan Meteorological Agency and universities for relatively large earthquakes and fault activities that occurred in the past, and tried to quantify the conceptual model. As a result, a more specific conceptual model could be constructed by combining geophysical methods such as seismic observation, as well as information based on conventional topographic and geological methods.
