California Active Faults

No License Restrictions

This resource contains data on active faults in California that are believed to be sources of M>6 earthquakes during the Quaternary (the past 1,600,000 years). This resource is a compilation of Quaternary Active Fault features compiled by the USGS in cooperation with the California Geological Survey and accessed on July 11, 2012 by the AZGS. The Quaternary Fault and Fold Database for the Nation can be accessed online at through a user-friendly interface developed by the U.S. Geological Survey. This is part of the first nationwide compilation to provide up-to-date and comprehensive geologically based information on known or suspected active faults. The data are available as a Web feature service, a Web map service, an ESRI Service Endpoint, and an Excel workbook for the National Geothermal Data System. Each feature in an active fault dataset (record or row in the worksheet) is characterized by a unique combination of features, as well as being physically connected or inferred to be connected spatially in the Earth. For mapped active faults, the deformation style is assumed to be brittle (as opposed to ductile). The workbook contains 6 worksheets, including information about the template, instructions on using the template, notes related to revisions of the template, resource provider information, the data, a field list (data mapping view), and vocabularies (data valid terms) used to populate the spreadsheet. Fields in the data table include FeatureURI, Name, FullName, ParentFeatureURI, Label, Description, Symbol, OtherID, SpecificationURI, FeatureType, GeologicHistory, RepresentativeAgeURI, YoungerAgeURI, OlderAgeURI, IntervalSince Movement, Shape, ObservationMethod, PositionAccuracyMeters, PositionAccuracy, Displacement, SlipRate, SlipAccumulationInterval, MovementType, MovementSense, DipDirection, DateMostRecentEvent, RecurrenceInterval, TotalSlip, Source and MetadataURI.--NGDS
