Earthquake Catalogs of the LArge-n Seismic Survey in Oklahoma dataset

This dataset release contains earthquake catalogs created using different association methods for the LArge-n Seismic Survey in Oklahoma dataset. These datasets can be used by researchers to further analyze the earthquakes in the array to better understand their behavior. The association methods applied here are as follows the Guassian Mixture Model Association (GaMMA) (Zhu et al., 2022), PhaseLink (Ross et al., 2019), the Graph Earthquake Neural Interpretation Engine (GENIE) (McBrearty and Beroza, 2023) and Rapid Earthquake Association and Location (REAL) code (Zhang et al., 2019). For detailed information please see the paper that accompanies this dataset (Pennington et al. 2024). Important notes though, the GaMMA dataset has a large number of false events so it should be used with caution. The PhaseLink dataset does not associate S-phase arrivals so the catalog will only include P-wave arrivals. We also include in this dataset the original detected phase arrivals that each of these catalogs were created from to allow any user to test and apply new methods to and later compare to our results.
