  • 2026:04 3D Discrete Element Modelling of Fluid Injection Induced Fault Slip in Argillaceous Rock – Mt.Terri Fault Slip Experiment

    SSM perspective Background and objective It is a well-known phenomenon that artificial increased in pore pressure at depth, due to subsurface fluid injection, can trigger earthquakes (Walsh and Zoback 2015, and references therein). Increased pore pressures at depth can also occur naturally, for instance due to the pressure changes imposed by a waxing and waning ice sheet. A geological...

  • 2026:05 Thermally Induced Fracture Slip in Crystalline Rock: Experimental and Numerical Studies and Safety Implications for Geological Disposal of Nuclear Wastes

    SSM perspective Background and objective High level radioactive waste, such as spent nuclear fuel, will continue to generate heat after the final disposal in an underground repository. The decay heat results in thermal expansion of the repository rock mass which can induce deformation of the fracture system. Near-field effects may involve thermally induced slip of a fracture crossing a...
