2019 Ridgecrest Earthquake Sequence Long-Term Hypocenter and Moment Tensor Catalog

There are two catalogs in this dataset produced for the study by Atterholt, Wilding, & Ross (2025): A relocated earthquake hypocenter location catalog made using PhaseNO (Sun et al., 2023) for phase picking, GaMMA (Zhu et al., 2022) for phase association, HypoSVI (Smith et al., 2021) for absolute location, and GrowClust (Trugman & Shearer, 2017) for cross-correlation-based relative relocation. A corresponding earthquake moment tensor catalog made using the picks from the hypocenter catalog and the Bayesian framework outlined in Wilding & Ross (2024). Citations: Atterholt, J., Wilding, J.
