The relations were established through velocity-stepping (VS) experiments on split basalt core subject to various stress, infill, and hydraulic conditions. The basalt...

... Abstract We report experimental research on frictional strength and stability properties of shale fractures during slip. Longmaxi shale, Green River shale and Marcellus shale are selected for constant-velocity and velocity-stepping fracture shear experiments. Combing with theoretical analysis...

... stick-slip instability on pre-existing faults, along which the frictional strength represents a lower limit on rock shear strength in the seismogenic layer. This paper proposes a new concept of earthquake activity on pre-existing discontinuities based upon a recently identified fan-structure dynamic...
