Description: Digital representation of major faults in Southern California depicted by Southern California Earthquake Data Center (SCEDC) on 'Faults of Southern California'. http://www.scecdc.scec.org/faultmap.html Original Abstract: This digital database contains the faults shown on the Fault Activity Map of California and Adjacent Areas by Charles W. Jennings published in 1994. The map shows the locations of known faults that can be portrayed at 1:750,000 scale and indicates the latest age when displacements took place according to available data. The displacements may have been associated with earthquakes or may have been the result of gradual creep along the fault surface. The faults are separated into five categories: historic, Holocene, late Quaternary, Quaternary, and pre-Quaternary. Many faults in Nevada and Baja California shown on the published map are not in this digital database. The late Cenozoic faults in the Foothills Fault Zone are included with the pre-Quaternary faults. Original Purpose: To provide information for those concerned with land use on or near geologic faults in California. Supplemental Information: This database should be used in conjunction with the published version of the Fault Activity Map of California and Adjacent Areas available from the California Department of Conservation, Division of Mines and Geology (DMG) by mail: P.O. Box 2980, Sacramento, CA 95812-2980 or by phone (916) 445-5716. The map is also available from DMG offices in San Francisco (415) 904-7707 and Los Angeles (213) 239-0878.

Initial editing of Quaternary faults was done by U.S. Geological Survey staff. Additional editing and final proofing was done by Division of Mines and Geology staff. The attribute accuracy was tested by overlaying the original mylars on plots of each category of faults to see that they match. Quantitative Attribute Accuracy Assessment: Attribute Accuracy Explanation: This database is a faithful digital representation of most faults on the Fault Activity Map of California and Adjacent Areas. Users of this database should be aware of the difference between precision and accuracy. While digital data can be reproduced precisely at any scale, the accuracy of the data remains constant. As the scale is increased from 1:750,000, uncertainty and errors in fault location remain the same. Also the user is cautioned that the faults in this database are not necessarily the same as those depicted on the 1:24,000-scale DMG Earthquake Fault Zone Maps. Although the author of the Fault Activity Map attempted to make the fault map consistent with the Earthquake Fault Zone Maps, the evaluation criteria for the maps are different so the depiction of faults may differ significantly. Faults in the Fault Activity Map and Geologic Map of California Databases - Fault locations in the digital databases for the Fault Activity Map and the Geologic Map of California are similar but not identical. The representation of faults in the digital database for the Geologic Map of California is the same as those of the Fault Map of California, published in 1975 (Jennings, 1985 p.56). Faults depicted on the Fault Activity Map of California and Adjacent Areas, published in 1994, were revised using the results of 20 years of research conducted since the earlier publication. The new map was redrafted and scribed on a new edition of the base map, which is significantly different from the previous version. Faults in the database for the Fault Activity Map are those of the 1994 map. Although the differences are not readily apparent on the printed versions of the maps, differences, particularly in location, will be obvious if the digital versions of the faults are superimposed. See Division of Mines and Geology Bulletin 201 (Jennings,1985) and An Explanatory Text to Accompany the Fault Activity Map of California and Adjacent Areas (Jennings,1994) for more information on the sources of the datasets. Logical Consistency Report: Dataset is consistent with the Fault Activity Map of California (Jennings, 1994). Completeness Report: The dataset contains major faults depicted by Southern California Earthquake Data Center (SCEDC) on 'Faults of Southern California' based on the Fault Activity Map of California (Jennings, 1994). Original Positional Accuracy: Horizontal Positional Accuracy: Horizontal Positional Accuracy Report: The faults were digitized at the same scale as the published map, 1:750,000 or 1 inch equals approximately 12 miles. The theoretical accuracy of the published map is about 0.012 inch, the width of the fault lines, which is equivalent to 232 meters (760 feet) on the ground. However, plotting and drafting errors can and do significantly increase the uncertainty. For example, a plotting error of a line width at 1:750,000 scale could cause a location error of 464 meters (approximately 1520 feet) on the ground.

Scanning, vectorization, and initial editing of the Quaternary faults were done by Richard Dart and Michael Machette of the U.S. Geological Survey in Denver. Additional editing was done by Diane Burns and Geoffrey Faneros of the Division of Mines and Geology (DMG) in Sacramento. The pre-Quaternary faults were digitized by Geoffrey Faneros and Jason Little of DMG. The late Cenozoic faults in the Foothills Fault Zone are included with the pre-Quaternary faults and were digitized by Jennifer Davis of DMG. George Saucedo and David Wagner of DMG did proofing of both the initial and the final editing.

SCEDC disclaimer - "These maps should not be considered as zoning guides, nor be used for risk assessment. Because of the sheer number of faults in southern California, this is not an exhaustive collection. The faults featured within this section were chosen typically because they are larger and/or exhibit more recent offset than others. Most, if not all, of this material has a certain level of uncertainty to it. Our understanding of faults is constantly expanding, and new faults and better data may be added to these maps as our knowledge about these structures advances."
