General friction and rate and state friction data of powdered fault gouge samples derived from outcrops of the Mai'iu Fault, Papua New Guinae, which is one of the world's most rapidly slipping low-angle normal faults, The experiments show that gouges from the shallowest portion of the fault zone are predominantly weak and velocity-strengthening, while fault rocks deformed at greater depths are stronger and velocity-weakening. Evaluating the geodetic and friction results together with geophysical and microstructural evidence for mixed-mode seismic and aseismic slip at depth, we find that the Mai'iu fault is most likely strongly locked at depths of ~ 5 -16 km and creeping updip and downdip of this region. Our results suggest that the Mai'iu fault and other active low-angle normal faults can slip in large (M > 7) earthquakes despite near-surface interseismic creep on frictionally stable clay-rich gouges.

The data is provided in 10 subfolders for 10 experiments/samples. Detailed information about the files in these subfolders as well as information on how the data is processed is given in the explanatory file Biemiller-et-al-2020-Data-Description.docx.
