Abstract:
This study focuses on the Pāpaku fault, a major splay fault in the Hikurangi prism which shows evidence of both brittle and ductile in-situ deformation. The Hikurangi subduction zone, located off the eastern coast of New Zealand's North Island, is known for regularly repeating slow slip events which occur at very shallow depths, possibly reaching the seafloor. We performed laboratory friction experiments on 8 intact core samples spanning the Pāpaku fault from 237-450 mbsf, recovered during IODP Expedition 375. The experiments were conducted at in-situ effective normal stress and driving velocities as low as the plate convergence rate of 5 cm/yr. Following the shearing experiments, the samples were analyzed for microstructure with scanning electron microscopy.
