Abstract:
We report on laboratory friction experiments spanning a range of slip velocities from plate-tectonic rates (cm/yr), to constrain the fault pre-stress, up to coseismic rates (m/s), to constrain the dynamic stress drop. The experiments used samples collected by scientific drilling at shallow depths (< 1 km) from a plate-boundary fault zone, the Alpine Fault in southern New Zealand. We tested Alpine Fault DFDP-1B fault gouge powder in intermediate- to high-velocity friction experiments at Durham University, United Kingdom. We sheared the sample at constant slip velocities of 0.0016, 0.013, 0.13, and 1.3 m/s in four separate experiments, where 1.3 m/s is considered to be a reasonable value for coseismic slip velocity.
