Abstract: This data set contains locations and information on faults and associated folds in the United States that are believed to be sources of M>6 earthquakes during the Quaternary (the past 1,600,000 years). On the website, maps of these geologic structures are linked to a database containing detailed descriptions and references. The database is intended to be the USGS?s archive for historic and ancient earthquake sources used in current and future probabilistic seismic-hazard analyses. Our website presents for the first time a single source that summarizes important information on paleoseismic (ancient earthquake) parameters. These data are compiled from thousands of journal articles, maps, theses, and other documents, as referenced herein. The database is designed to serve a variety of needs, both in terms of the user community and methods of delivering the data.

FGDC and ESRI Metadata:

Metadata elements shown with blue text are defined in the Federal Geographic Data Committee's (FGDC) Content Standard for Digital Geospatial Metadata (CSDGM). Elements shown with green text are defined in the ESRI Profile of the CSDGM. Elements shown with a green asterisk (*) will be automatically updated by ArcCatalog. ArcCatalog adds hints indicating which FGDC elements are mandatory; these are shown with gray text.

Abstract:
This data set contains locations and information on faults and associated folds in the United States that are believed to be sources of M>6 earthquakes during the Quaternary (the past 1,600,000 years). On the website, maps of these geologic structures are linked to a database containing detailed descriptions and references. The database is intended to be the USGS?s archive for historic and ancient earthquake sources used in current and future probabilistic seismic-hazard analyses. 

Our website presents for the first time a single source that summarizes important information on paleoseismic (ancient earthquake) parameters. These data are compiled from thousands of journal articles, maps, theses, and other documents, as referenced herein. The database is designed to serve a variety of needs, both in terms of the user community and methods of delivering the data.

Purpose:
Starting in the early 1970s, mainly in response to national concerns about the siting of nuclear reactors, scientists needed to locate active and Quaternary faults and document their characteristics. 
The descriptions contain information on geographic, geologic, and paleoseismic parameters that are deemed critical to making geologic-based assessments of seismic hazards. In addition, we provide narrative comments that clarify, justify, or expound upon these parameters. Many of the comments in the database provide justification for the paleoseismic parameters that were chosen to characterize the faults and folds.

Supplemental information:
details about each fault are available through the online database at http://qfaults.cr.usgs.gov/

Data set credit:
The project coordinator is Michael Machette (USGS). The database structure was created by Kathy Haller (USGS) and an early version of the web interface and search engines were created by Larry Mayer (formerly of the University of Miami at Oxford, Ohio). The GIS data was engineered and maintained by Richard Dart (USGS). The fault and fold traces were digitized mainly by Richard Dart, with help from Dean Hancock*. Static maps were made by Susan Rhea (USGS), Richard Dart, and Damon Sather*. The graphic web browser and ArcIMS module (still under development) were created by Susan Rhea, Damon Sather*, Karen Morgan*, and John Cox*. Much of the reference database and entry of data into the text database was done with the able assistance of Philly Morrow, Meredith Frey, and Kelli Clark (*, all former student interns or contractors to the USGS).

Compilers and cooperators are listed on the web page (http://earthquake.usgs.gov/qfaults/contrib.html). Compilers are those who described faults or folds for the database. Cooperators are those who assisted with the development of digital fault data (traces), the database structure, or the geographical information system (GIS) interfaces.

Data Quality Information:


Attribute accuracy:
Attribute accuracy report:
Fault characteristics, even where known in detail, are reported in broad categories (for example "age less than 1,600,000 years"). The textual database contains more specific information about each fault where details were available in published literature.

Logical consistency report:
Due to substantial differences in the geological setting and tectonic activity, the central and eastern United States appear to have fewer faults active in the Quaternary. This is partly a real phenomena (the western US has more tectonic activity) and partly a detection problem. For example, the glacial sediments that cover much of the eastern midwest states conceal the evidence we would use to infer movement along underlying faults in the Quaternary

Completeness report:
The database does not include faults in Alaska or Hawaii at present. California database is incomplete, not all faults are included.

Positional accuracy:
Horizontal positional accuracy:
Horizontal positional accuracy report:
Locations of faults were taken from published literature; these investigations were carried out at a variety of scales of observation, hence some faults will be located more precisely and accurately than others. In general the locations are accurate as observed on a 1:250,000 scale map, or approximately 450 feet.

Process description:
Starting in the early 1970s, mainly in response to national concerns about the siting of nuclear reactors, scientists needed to locate active and Quaternary faults and document their characteristics. This broad research initiative resulted in new maps and studies of Quaternary faults. State (Jennings, 1975; Witkind, 1975; 1975; 1975; 1976; Menges and Pearthree, 1983), regional (Nakata and others, 1982), and National (Howard and others, 1978) maps were compiled to show the location and relative timing of major faults. These map compilations, however, did not provide much supporting data. Subsequent state-scale compilations, such as those by Johns and others, (1982), Stickney and Bartholemew (1987), and Hecker (1993) provided some supporting database and were the first true fault compilations. The Quaternary fault and fold data for the United States has relied heavily on the past contributions, and on new efforts by State geological surveys and the U.S. Geological Survey. 
The most recent effort began in 1990 in support of the International Lithosphere Program (ILP), which formed Working Group II-2. Its main objective was to compile a World Map of Active Faults (Vladimir Trifonov, chairman). In 1992, the USGS agreed to help compile maps and fault descriptions for countries in the Western Hemisphere (North, Central, and South America, as well as Australia and New Zealand). This work continues to date, with many of the compilations for Central and South America countries having been published. 

In 1993, the U.S. Geological Survey began developing a database for Quaternary faults and folds for the United States in earnest, largely supported by NEHRP but with significant support from many State surveys. This product is more robust than the ILP products, mainly owing to the vast amount of data that has become available within the U.S. in the past 20-30 years and the importance that this data plays in regional and national seismic-hazard assessments (Petersen and others, 1996; Frankel and others, 1996). 

For this compilation, we have limited our compilation to synthesis of published literature relevant to the United States. Our definition of published literature includes typical sources (journals and maps), as well as M.S. theses and Ph.D. dissertations, governmental contract reports (which includes many NEHRP-sponsored studies), abstracts, and open-file (preliminary) reports. We generally do not cite unpublished field mapping, field notes, and other gray-literature reports that are not generally available to the public. The data presented in the compilation are extensively referenced using the standard USGS reference style, with the exception of attaching a unique number to each cited reference for convenience. This numeric identifier allows us to clearly cite multiple-same year publications for authors.
