Summary

Fault heterogeneities such as bumps, bends, and stepovers are commonly observed on natural faults but challenging to recreate under controlled laboratory conditions. We study deformation and microseismicity of a 76 mm-diameter Westerly granite cylinder with a sawcut fault with known frictional properties. An idealized asperity is added by emplacing a precision-ground 21 mm-diameter solid granite dowel that crosses the center of the fault at right angles. This intact granite ‘pin’ provides a strength contrast that resists fault slip. Upon loading to 80 MPa in a triaxial machine, we first observed a M -4 slip event that ruptured the sawcut fault, slipped 40 mm, but was halted by the granite pin. With continued loading, the pin failed [...]
