Development of rock deformation techniques under high-pressure and high-temperature conditions

— Evaluation of long-term geological processes by a compressed timescale process model —

Abstract

The reliability of earthquake forecast information is important for disaster mitigation in our society. A physical model of the earthquake generation process was constructed to improve the reliability of earthquake forecast information. We proposed a model based on the information extracted from geological surveys. Our model was evaluated using experimental techniques in the laboratory. During the experimental study, we considered two disparities between laboratory and natural conditions, which were differences in environmental conditions and timescale. A new experimental rock deformation technique was developed that unifies previous and newly developed techniques. Long-term geological processes were evaluated by a process model operating over a compressed timescale.
