A new catalog is assembled from several preexisting catalogs.  Uniform moment magnitudes and related parameters for estimating unbiased seismicity rates are calculated.  Duplicates, explosions, mining-related earthquakes, and induced earthquakes are flagged, and the catalog is declustered.  Distinct catalogs are made for the central and eastern U.S. and the western U.S.  This data set is the master earthquake catalog for the western U.S., for use outside the UCERF3 zone (Catalog B)", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/F7P26X4R", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}, {"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.5b180f06e4b092d96521998b.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_5b180f06e4b092d96521998b", "keyword": ["Arizona", "California", "Colorado", "Earthquake", "Hazard", "Idaho", "Induced", "Montana", "Natural", "Nevada", "New Mexico", "Oklahoma", "Oregon", "Seismic", "Texas", "USA", "USGS:5b180f06e4b092d96521998b", "United States", "Utah", "Washington", "Wyoming"], "modified": "2026-03-13T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-128.000, 22.020, -96.270, 51.911", "theme": ["geospatial"], "title": "Western U.S.: Master earthquake catalog for use outside the UCERF3 zone (Catalog B)"}
