Abstract:
This report presents a preliminary map and database of Quaternary deposits and liquefaction susceptibility for the nine-county San Francisco Bay region, together with a digital compendium of ground effects associated with past earthquakes in the region. The report consists of (1) a spatial database of fivedata layers (Quaternary deposits, quadrangle index, and three ground effects layers) and two text layers (a labels and leaders layer for Quaternary deposits and for ground effects), (2) two small-scale colored maps (Quaternary deposits and liquefaction susceptibility), (3) a text describing the Quaternary map, liquefaction interpretation, and the ground effects compendium, and (4) the databse description pamphlet.
The nine counties surrounding San Francisco Bay straddle the San Andreas fault system, which exposes the region to serious earthquake hazard (Working Group on California Earthquake Probabilities, 1999). Much of the land adjacent to the Bay and the major rivers and streams is underlain by unconsolidated deposits that are particularly vulnerable to earthquake shaking and liquefaction of water-saturated granular sediment.
This new map provides a modern and regionally consistent treatment of Quaternary surficial deposits that builds on the pioneering mapping of Helley and Lajoie (Helley and others, 1979) and such intervening work as Atwater (1982), Helley and others (1994), and Helley and Graymer (1997a and b). Like these earlier studies, the current mapping uses geomorphic expression, pedogenic soils, and inferred depositional environments to define and distinguish the map units. In contrast to the twelve map units of Helley and Lajoie, however, this new map uses a complex stratigraphy of some forty units, which permits a more realistic portrayal of the Quaternary depositional system. The two colored maps provide a regional summary of the new mapping at a scale of 1:275,000, a scale that is sufficient to show the general distribution and relationships of the map units but cannot distinguish the more detailed elements that are present in the database.
The report is the product of years of cooperative work by the USGS National Earthquake Hazards Reduction Program (NEHRP) and National Cooperative Geologic Mapping Program, William Lettis and & Associates, Inc. (WLA) and, more recently, by the California Division of Mines and Geology as well. An earlier version was submitted to the Geological Survey by WLA as a final report for a NEHRP grant (Knudsen and others, 2000). The mapping has been carried out by WLA geologists under contract to the NEHRP Earthquake Program (Grants #14-08-0001-G2129, 1434-94-G-2499, 1434-HQ-97-GR-03121, and 99-HQ-GR-0095) and with other limited support from the County of Napa, and recently also by the California Division of Mines and Geology. The current map consists of this new mapping and revisions of previous USGS mapping.
Purpose:
Map delineation of the different types and ages of Quaternary deposits supports evaluation of susceptibility to liquefaction, the immediate application of the work, but serves many other purposes as well. It provides a framework for interpreting the architecture and history of the Quaternary sedimentary basins, which is used in estimating earthquake shaking and modeling the groundwater system. The mapping is also useful in constraining the ages and histories of offsetting faults, in guiding geotechnical investigations, and in other engineering, geologic, and archeological applications.
Supplemental_Information:
This report has undergone two scientific peer reviews, one digital database review, and review of the digital files for functionality.
This report presents a preliminary map and database of Quaternary deposits and liquefaction susceptibility for the nine-county San Francisco Bay region, together with a digital compendium of ground effects associated with past earthquakes in the region. The report consists of (1) a spatial database of five data layers (Quaternary deposits, quadrangle index, and three ground effects layers) and two text layers (a labels and leaders layer for Quaternary deposits and for ground effects), (2) two small-scale colored maps (Quaternary deposits and liquefaction susceptibility), (3) a text describing the Quaternary map, liquefaction interpretation, and the ground effects compendium, and (4) the database description pamphlet. See the revision list (of00-444_2x) or Open-File pamphlet (of00-444_1x) for further details.

Process_Description:
The Quaternary deposits database was compiled digitally in vector form in ARC/INFO as individual 7.5-minute (126) and 0. 5x1.0-degree (2) quadrangles at scales of 1:24,000 and 1:100,000, respectively. The 1:100,000 materials were modified from previously released spatial databases for the San Francisco and Napa 0.5x1.0-degree quadrangles (Knudsen and others, 1997, and Sowers and others, 1998, respectively), and the 1:24,000 materials were variously modified from previous work or newly digitized, depending on the degree of remapping involved (see part 3, Description of Mapping). These many individual pieces were converted to UTM projection and assembled into a single regional layer. Remaining quadrangle boundary problems were resolved where possible, although some remain where the status of mapping differs across the boundary. The resulting spatial database retains the resolution of the input parts, some at 1:24,000, some at 1:100,000. Much of the fine detail in the spatial database is too small for legible portrayal at the regional scale of the colored maps (1:275,000).
The ground-effects database was compiled digitally in vector form from 1:100,000 and 1:24,000 materials, including relocation at 1:24,000 of 1:250,000-scale map features based on text descriptions of historic effects (see Appendix C of part 3, Description of Mapping). The Loma Prieta dataset was digitized directly in ARC/INFO, whereas the historic dataset was digitized in MapInfo and subsequently converted to ARC/ INFO. Points and lines for the historic and Loma Prieta datasets were combined into a single vector layer, but the polygons could not be (some polygons overlap), and these remain separate.
The vector lines in the quadrangle database were generated automatically with high precision in ARC/INFO as a latitude/ longitude grid, densified to a vertex spacing of 0.005 degrees along all the lines, and reprojected to UTM .
The ARC layers (coverages) are stored in UTM projection, but the shape files are in decimal degrees of longitude and latitude, prepared by projecting and converting the primary UTM coverages.
Digital compilation of the many 7.5-minute quadrangles involved was carried out over a period of several years, during which one or more quadrangles each were digitized by Andrew Barron, Gregg Beukelman, Joe Colgan, Jennifer Davis, Scott Graham, Marjorie Lucks, Tom May, David Ramsey, Carrie Randolph, Joel Robinson, Adam Soule, and Jim Thordsen. Digital compilation of the 0.5° x 1° quadrangles was done separately for the reports by Knudsen and others (1997) and Sowers and others (1998).
