This dataset contains the final technical report and closeout presentation for the project A Strain Sensing Array to Characterize Deformation at the Utah FORGE Site, carried out from 2021 to 2025 by Clemson University in collaboration with the U.S. Geological Survey and UNAVCO. The report documents the design, deployment, operation, and analysis of a shallow, high-resolution tensor strainmeter array used to measure deformation associated with hydraulic stimulation at Utah FORGE, including instrument fabrication, field installation in unconsolidated alluvium, laboratory validation of high-temperature and high-pressure strainmeter designs, processing and calibration of strain data, and interpretation of measured strain signals during stimulation experiments in 2022 and 2024.
