Laboratory Acoustic Emissions Reveal Stress Rotation From Preparation Processes Toward Fault Slip on Varying Surface Roughness in Granular Materials

Abstract We investigate the influence of fault roughness on physical damage prior to large laboratory rock failure and the evolution of the local stress field surrounding the fault zone as macroscopic shear slip approaches. To achieve this, we analyze acoustic emission (AE) data from displacement‐dr...
