Utah FORGE: Laboratory Shear Experiments Linking Fault Roughness, Friction, Permeability, and P-Wave Characteristics

Published by Pennsylvania State University | Department of Energy | Catalog Last Checked: June 04, 2026 at 09:07 PM | Dataset Last Updated: June 04, 2026 at 05:45 PM
This dataset contains results from five laboratory shear experiments on gneiss and granitoid samples from the Utah FORGE site, conducted at Penn State University. The experiments investigate links between fault surface roughness, frictional behavior, permeability, and P-wave acoustic properties during controlled shear deformation. The associate publication is linked here. Data include mechanical and acoustic time-series measurements, rate-and-state friction model outputs, and roughness scans acquired using a Keyence optical profilometer. Mechanical parameters such as stress, displacement, friction, and permeability are provided alongside P-wave velocity, amplitude, and time-of-flight shifts. Roughness data are in .cag format, compatible with Keyence analysis software, and time-series and model data are in MATLAB .mat format. All variables and units are described in the accompanying README file.
