FAULT ZONES MAPS OF CALIFORNIA,NORTHERN AND EASTERN REGION

INTRODUCTION

The Alquist-Priolo Earthquake Fault Zoning (AP) Act was passed in 1972 as aresult of the destructive 1971 San Fernando earthquake. The AP Act addresses theseismic hazard of surface fault rupture by prohibiting the placement of most structures forhuman occupancy across traces of active faults. The AP Act addresses the seismic hazardof surface fault rupture by prohibiting the placement of most structures for humanoccupancy across traces of active faults. The Act also requires sellers and real estateagents to inform buyers whether real property being sold is within a state-designated Earthquake Fault Zone. The Department of Conservation, Division ofMines and Geology has issued 544 regulatory maps as of March 1, 2000 at a scale of1:24,000. These maps, designated as Earthquake Fault Zones maps, are issued in order toassist cities and counties in avoiding the hazard of surface fault rupture. For moreinformation on the AP Act refer to the enclosed .pdf version of Special Publication (SP)42, Fault-Rupture Hazard Zones in California.

The statewide collection of digital images of AP Earthquake Fault Zone maps isdivided into three geographic regions: Southern Region, Central Coastal Region, andNorthern and Eastern Region. This CD contains digital images of Official Maps ofEarthquake Fault Zones (EFZ) affecting the Northern and Eastern Region, includingAlpine, Butte, Humboldt, Inyo, Lassen, Mendocino, Modoc, Mono, Shasta, and Siskiyoucounties, and is current as of March 1, 2000. Updates of digital versions of EarthquakeFault Zone maps will be available on the Department of Conservation, Division of Minesand Geology’s (DMG) web site as new maps are issued and current maps are revised.New and/or revised EFZ maps generally are issued about once a year. Releaseannouncements of both preliminary review maps and official EFZ maps can be found atwww.consrv.ca.gov/dmg/rghm.

CD CONTENTS

Contents of this CD include 169 pdf image files of Official Maps of Alquist-Priolo Earthquake Fault Zones and metadata files for the Northern and Eastern Region. Special Publication (SP) 42, Fault-Rupture Hazard Zones in California (1999 reprinted versionof 1997 edition), is included as a pdf file. This CD-ROM contains four tables in pdf fileformat. Table 1 is an alphabetical listing of EFZ map names listing the affectedcounty(ies) and city (ies). Table 2 lists the 36 affected counties and the specific EFZmaps that affect that county. Table 3 lists the 100 affected cities and the specific EFZmaps affecting that city. Table 4 lists the counties contained in each of the CD-ROMsets. Please note that the tables of affected counties (Table 2) and affected cities(Table 3) are correct as of March 2000, but may be subject to change as new citiesare created, city boundaries are expanded, or new zones are established. Currentlists of counties and cities affected by AP EFZs are located at DOC\DMG’s websitewww.consrv.ca.gov/dmg/rghm.

The EFZ files contained in this CD are current as of March 1, 2000. Please checkthe DMG website at www.consrv.ca.gov/dmg/rghm for current information on new andrevised EFZ maps.

Original AP EFZ maps (original hardcopy maps) consist of a topographic basemap at 1:24,000 scale and a clear-film overlay containing turning points defining EFZboundaries and fault traces used to establish the EFZ. Fault traces consist of five linetypes:

Solid line: accurately located traceLong-dashed line: approximately located traceShort-dashed line: inferred fault traceDotted line: concealed fault traceThin dashedand dotted line: indicates aerial photo lineament (symbol generally not used

after 1981)Query: indicates additional uncertainty

The Act was initially designated Alquist-Priolo Special Studies Zones Act and officialregulatory maps were known as maps of Special Studies Zones. The name was changedJanuary 1, 1994 to Alquist-Priolo Earthquake Fault Zoning Act and the official maps arecurrently referred to as maps of Earthquake Fault Zones. Title blocks of maps issuedprior to 1994 refer to the older name Special Studies Zones. These pre-1994 maps havebeen reproduced for this CD without the stamp referring to the name change.

DIGITAL COMPILATION

The original hardcopy maps used to reproduce Official Maps of Earthquake FaultZones were the basis for developing these digital image files. Each hardcopy mapconsists of two layers: a solid line clear film topographic base and a clear film overlaycontaining EFZ zones and fault traces. Each layer was scanned at 400 dpi using anAnatech large-format scanner. The base and overlay images were translated to .pcxgrayscale images and resolution reduced to 266 dpi and reduced to 50% of the physicalimage size. These reductions in size and resolution allowed smaller file sizes withnegligible loss of image quality. The resulting .pcx files were then registered, enhanced,and processed to .pdf files using Adobe Photoshop and Adobe Acrobat The finalAcrobat images are optimized to read in Adobe Acrobat Reader, version 4.0.

GETTING STARTED

You must have Adobe Acrobat Reader 4.0 installed before you can view the EFZimages. The .pdf files on this CD-ROM are exact images of the Official Maps ofEarthquake Fault Zones issued by the Division of Mines and Geology. These images areintended for viewing and printing at a scale of 1 inch equals 2,000 feet. Any furtherenlargement could result in a lesser quality image.

SETTING UP YOUR ACCROBAT READER

Inserting the CD-ROM (only when using a windows pc) will automatically open awindow with navigation buttons to start your session. When first opening the AcrobatReader, select “file”, “preferences”, “general” and unselect the option to open cross-doclinks in the same window. Deselecting this option allows multiple window operation.You may also need to configure your Internet Browser using weblink preferences inAcrobat Reader.

NAVIGATING THE CD FILES

The individual county index maps show all of the EFZ maps that affect thatcounty. At the main index map, selecting either a specific county on the index map, or thecounty name in the list to the left will access the specific county index map. If your viewis showing the thumbnails or bookmarks as a list, you may also double-click these tonavigate to the desired county.

Each county map has arrow indicators to access the adjacent county. However, ifthe arrow points to a county or map not contained in this CD-ROM, nothing will happen.An Acrobat sticky-note will indicate what action to take. You will have to purchase theCD-ROM that contains that county from the Division of Mines and Geology. Refer toTable 4 for a list of counties contained in each CD-ROM set.

To find a specific EFZ map, you need to know the geographic location of thearea, the city name, or the quadrangle map name. Affected cities are listed in Table 3 andare shown to the left of each county index. Clicking on the city name in this list on the

5

county index maps will access the correct EFZ map. If an incorporated city is not listedin Table 3, it is not affected by an EFZ. If an EFZ on a specific quadrangle map extendsto the adjacent quadrangle contained in this CD-ROM, clicking on the area outside of themap border will directly access the adjacent EFZ map.

SELECTING AND PRINTING A SPECIFIC AREA ON AN EFZ MAP

Any portion of these maps can be selected and copied for use in any applicationusing the paste command. To select an area, open the document and zoom to 100% at thearea of interest. Hold the mouse button down on the “grab text” tool button, which willexpand to three buttons. Choose the “grab graphics” tool button (last one on the right).Using this tool, select your area of interest. Now use the zoom box to enter “200%” aszoom number, then copy the selection. Using 200% will result in a image atapproximately the original map scale (1:24,000) that can be copied into the desiredapplication.

To print the selected area at a scale of 1 inch equals 2,000 feet requires printing at200% enlargement. The image was reduced 50% to reduce file size attributes, whilemaintaining image quality for viewing. Printing at 100% of image size will result in aprinted scale of approximately 1 inch equals 4,000 feet.

ACCURACY AND LIMITATIONS OF THIS DATABASE

Original hardcopy AP EFZ maps were compiled over the past 25 years at a scaleof 1:24,000. Digital EFZ files were created by scanning the hardcopy maps used togenerate Official EFZ maps. As the scale of the digital image is increased from 1:24,000,uncertainty and errors in fault location and EFZ boundary and turning point locationsremain the same. U.S. Geological Survey base map standards provide that 90 percent ofcultural features be located within 40 feet (horizontal accuracy) at the scale of 1:24,000.Turning point locations were placed on the original hardcopy maps using the criteria ofestablishing the desired setback distance from the fault zone and using a readilyidentifiable feature on the ground. However, the turning points and connecting EFZboundaries have not been surveyed to verify their mapped positions. The typical width ofthe turning point dot is between 40-50 feet at 1:24,000 scale. In addition, the width of theEFZ boundary at 1:24,000 is about 25 feet. Therefore, the actual location of EFZboundaries should be considered to be no better located than ± 50 feet.

Description – Data Quality Information

Abstract:

This data set is comprised of lines that form fault traces and regulatoryzone boundaries of areas where surface fault rupture previously hasoccurred, or where local topographic and geological conditions indicatea potential for permanent ground displacements such that mitigation byavoidance as stated in Public Resources Code Section 2621.5 would berequired.

Purpose:

These maps will assist cities and counties in fulfilling their responsibilityto prohibit the location of developments and structures for humanoccupancy across the trace of active faults as required by the Alquist-Priolo Earthquake Fault Zoning Act (Public Resources Code Sections2621-2630). These maps will also assist those acting as an agent for aseller of real property located in a delineated earthquake fault zone, orthe seller if they are acting without an agent, to disclose to anyprospective purchaser that fact that a property is located within adelineated fault zone.
