PARRISH, PH.D. STATE GEOLOGIST SPECIAL PUBLICATION 42 FAULT-RUPTURE HAZARD ZONES IN CALIFORNIA Alquist-Priolo Earthquake Fault Zoning Act With Index to Earthquake Fault Zones Maps by WILLIAM A. BRYANT and EARL W. HART Geologists Interim Revision 2007 California Department of Conservation California Geological Survey 801 K Street, MS 12-31 Sacramento, California 95814 PREFACE The purpose of the Alquist-Priolo Earthquake Fault Zoning Act is to regulate development near active faults so as to mitigate the hazard of surface fault rupture. This report summarizes the various responsibilities under the Act and details the actions taken by the State Geologist and his staff to implement the Act. This is the eleventh revision of Special Publication 42, which was first issued in December 1973 as an “Index to Maps of Special Studies Zones.” A text was added in 1975 and subsequent revisions were made in 1976, 1977, 1980, 1985, 1988, 1990, 1992, 1994, and 1997. The 2007 revision is an interim version, available in electronic format only, that has been updated to reflect changes in the index map and listing of additional affected cities. In response to requests from various users of Alquist-Priolo maps and reports, several digital products are now available, including digital raster graphic (pdf) and Geographic Information System (GIS) files of the Earthquake Fault Zones maps, and digital files of Fault Evaluation Reports and site reports submitted to the California Geological Survey in compliance with the Alquist-Priolo Act (see Appendix E). -

Fault Structure and Mechanics of the Hayward Fault, California, from Double-Difference Earthquake Locations Felix Waldhauser1 and William L
JOURNAL OF GEOPHYSICAL RESEARCH, VOL. 107, NO. B3, 10.1029/2000JB000084, 2002 Fault structure and mechanics of the Hayward Fault, California, from double-difference earthquake locations Felix Waldhauser1 and William L. Ellsworth U.S. Geological Survey, Menlo Park, California, USA Received 1 December 2000; revised 13 June 2001; accepted 18 August 2001; published 28 March 2002. [1] The relationship between small-magnitude seismicity and large-scale crustal faulting along the Hayward Fault, California, is investigated using a double-difference (DD) earthquake location algorithm. We used the DD method to determine high-resolution hypocenter locations of the seismicity that occurred between 1967 and 1998. The DD technique incorporates catalog travel time data and relative P and S wave arrival time measurements from waveform cross correlation to solve for the hypocentral separation between events. The relocated seismicity reveals a narrow, near-vertical fault zone at most locations. This zone follows the Hayward Fault along its northern half and then diverges from it to the east near San Leandro, forming the Mission trend. The relocated seismicity is consistent with the idea that slip from the Calaveras Fault is transferred over the Mission trend onto the northern Hayward Fault. The Mission trend is not clearly associated with any mapped active fault as it continues to the south and joins the Calaveras Fault at Calaveras Reservoir. In some locations, discrete structures adjacent to the main trace are seen, features that were previously hidden in the uncertainty of the network locations. The fine structure of the seismicity suggests that the fault surface on the northern Hayward Fault is curved or that the events occur on several substructures. -

MAPS SHOWING RECENTLY ACTIVE FAULT BREAKS ALONG the SAN ANDREAS FAULT from MUSSEL ROCK to the CENTRAL SANTA CRUZ MOUNTAINS by Earl H
U.S. DEPARTMENT OF THE INTERIOR U.S. GEOLOGICAL SURVEY MAPS SHOWING RECENTLY ACTIVE FAULT BREAKS ALONG THE SAN ANDREAS FAULT FROM MUSSEL ROCK TO THE CENTRAL SANTA CRUZ MOUNTAINS, CALIFORNIA By E. H. Pampeyan Menlo Park, California Open-File Report 93-684 This report is preliminary and has not been reviewed for conformity with U.S. Geological Survey editorial standards or with the North American Stratigraphic Code. Any use of trade, product, or firm names in this publication is for descriptive purposes and does not imply endorsement by the U.S. Government. 1995 MAPS SHOWING RECENTLY ACTIVE FAULT BREAKS ALONG THE SAN ANDREAS FAULT FROM MUSSEL ROCK TO THE CENTRAL SANTA CRUZ MOUNTAINS by Earl H. Pampeyan PURPOSE OF THIS MAP This map shows the location of lineaments and other geomorphic features interpreted to be the result of historic or relatively recent breaks within the San Andreas Fault Zone. It was compiled primarily to provide information for those concerned with land use and development on or in the fault zone, but it should also be useful in scientific studies of faulting and earthquakes. The lines on the map mark the location of suspected displacements of the ground surface by rupture along the San Andreas Fault. Map users should keep in mind that these lines are primarily guides for locating fault traces on the ground and are not necessarily located with the precision needed for every engineering or land-use project. THE SAN ANDREAS FAULT AND FAULT ZONE The San Andreas Fault Zone is a major structural break in the earth's crust that can be traced for more than 600 miles from the head of the Gulf of California in northern Mexico through western California. -
City of Milpitas General Plan
SEISMIC AND SAFETY ELEMENT Purpose State law requires "... safety element for the protection of the community from any unreasonable risks associated with the effects of seismically induced surface rupture, ground shaking, ground failure, ... dam failure; slope instability leading to mudslides and landslides, subsidence, liquefaction and other seismic hazards identified pursuant to Chapter 7.8 of the Public Resources Code and other geologic hazards known to the legislative body; flooding; and wild land and urban fires... " Relationship to Other Elements Issues related to the storage, handling and transportation of hazardous goods are addressed in Section 4.8: Waste Management and Recycling. 5-1 MILPITAS GENERAL PLAN 5-2 SEISMIC AND SAFETY ELEMENT 5.1 Seismic and Geologic Hazards The Hillside Area is located in the foothills of the Diablo Range and consists of a series of parallel hills and valleys oriented generally northwest/southeast. The rounded hills in the western portion of the Hillside Area form a band about one mile wide with a maximum elevation of about 1,270 feet. Spring Valley, in the central portion of the Area, is roughly one-quarter mile wide and two and a half miles long. The central portion of the valley is relatively flat and has an elevation of about 600 feet. Along the eastern boundary of the Hillside Area rise the steep western slopes of Los Buellis Hills, where the elevation ranges from roughly 800 feet to 2,337 feet at Monument Peak in the north. Background information in this section is extracted from Geotechnical Hazards Evaluation, City of Milpitas (1987). The report is based on compilation of published geologic and soils maps, data from unpublished geotechnical reports, and interpretation of stereoscopic aerial photographs.
