    • Utah FORGE: Focal Mechanism Catalog from Stage 3 of the April 2022 Stimulation Test

    Metadata Updated: September 17, 2025

    This submission includes focal-mechanism solutions derived from the Utah FORGE April 2022 Stage-3 stimulation. Waveforms were extracted around each event (short windows bracketing origin times) from the downhole three-component arrays in wells 58-32, 78-32, and 56-32 and the surface station UU.FORK; an initial Stage-3 catalog of several thousand located events was narrowed to ~1,200 preselected events and processed to produce a final high-quality set of 717 focal mechanisms.

    Methods combined automated phase picking with a noise-resistant deep-learning polarity classifier, simple amplitude-ratio measurements around arrivals, and Bayesian moment-tensor inversion using MTfit. Polarities and amplitude ratios were weighted by per-measurement confidence, posterior ensembles were sampled to quantify uncertainty, and solutions with low angular uncertainty (Kagan angle < 20 degrees) form the distributed high-quality catalog.
