There are two adjustments to the algorithm described by Thompson and others (2014), which is built on the geology-based Vs30 map by Wills and Clahan (2006). In this data release, we use the Wills and others (2015) updated geology-based Vs30 map. The second change is that we have adjusted the kriging procedure so that measured Vs30 values do not affect the predictions across distinctly different geologic units.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/F7JQ108S", "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.5a5fa029e4b06e28e9bfc43a.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_5a5fa029e4b06e28e9bfc43a", "keyword": ["California", "Earthquake Hazards Program", "GHSC", "Geologic Hazards Science Center", "USGS", "USGS:5a5fa029e4b06e28e9bfc43a", "United States", "earth science", "earthquake hazard", "geophysics", "seismic hazard", "seismology", "tectonic"], "modified": "2022-07-12T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-124.501041667, 32.498958335, -114.098958335, 42.101041667", "theme": ["geospatial"], "title": "An Updated Vs30 Map for California with Geologic and Topographic Constraints (ver. 1.1, July 2022)"}
