The proceedings show a good understanding of the processes and events that can affect crystalline rocks and, although there is less confidence in predicting exactly when and where such events will occur and the volume of rock that will be affected, the extent of the impacts on a geological repository can be confidently addressed using bounding approaches supported by geological information from similar sites around the world.

Examples of Key Processes Affecting the Geosphere for Crystalline Rock
Nuclear Energy Agency
We define the structure of a methodology being developed by NUMO to assess the likelihood that volcanic or rock deformation processes could significantly affect sites that may emerge from the Japanese volunteer siting process. Simple criteria are used to exclude clearly unsuitable areas at the outset: the present methodology is developing probabilistic techniques to look at likelihood in nonexcluded areas. These are based on scientific models for the occurrence of volcanism and a range of proxy indicators for potential future rock deformation.
