Deep Underground Science and Engineering, EarlyView.The tensile strength of granite, a proposed host for nuclear waste, degrades severely above 400°C. We link this to specific microcracking patterns captured by acoustic emission, establishing a scientific basis for assessing repository safety under thermal load.

Seismic performance of buckling‐restrained brace outrigger system in various configurations
Japan Architectural Review, 2019 The outrigger system is deemed an effective solution for mitigating the seismic responses of tall core‐tube‐type buildings. By incorporating a buckling‐restrained brace (BRB) in the outrigger system (BRB‐outrigger), the BRB‐outrigger reduces seismic ...

Deep Underground Science and Engineering, EarlyView.Fault slip can occur ahead of the injection pressure front due to poroelastic stress. Our model captures the interaction of pressure, stress, and friction, providing new insights into injection‐induced seismicity and post‐injection fault slip. Shut‐in operations can either mitigate or accelerate seismic events depending on fault conditions and ...
