I Final Technical Report United States Geological Survey National Final Technical Report United States Geological Survey National Earthquake Hazards Reduction Program - External Research Grants Award Number 08HQGR0140 Third Conference on Earthquake Hazards in the Eastern San Francisco Bay Area: Science, Hazard, Engineering and Risk Conference Dates: October 22nd-26th, 2008 Location: California State University, East Bay Principal Investigator: Mitchell S. Craig Department of Earth and Environmental Sciences California State University, East Bay Submitted March 2010 Summary The Third Conference on Earthquake Hazards in the Eastern San Francisco Bay Area was held October 22nd-26th, 2008 at California State University, East Bay. The conference included three days of technical presentations attended by over 200 participants, a public forum, two days of field trips, and a one-day teacher training workshop. Over 100 technical presentations were given, including oral and poster presentations. A printed volume containing the conference program and abstracts of presentations (attached) was provided to attendees. Participants included research scientists, consultants, emergency response personnel, and lifeline agency engineers. The conference provided a rare opportunity for professionals from a wide variety of disciplines to meet and discuss common strategies to address region-specific seismic hazards. The conference provided participants with a comprehensive overview of the vast amount of new research that has been conducted and new methods that have been employed in the study of East Bay earthquake hazards since the last East Bay Earthquake Conference was held in 1992. Topics of presentations included seismic and geodetic monitoring of faults, trench-based fault studies, probabilistic seismic risk analysis, earthquake hazard mapping, and models of earthquake rupture, seismic wave propagation, and ground shaking. Updated estimates of economic losses due to a major earthquake in the East Bay were presented. Engineering studies included examples of seismic design and retrofit of buildings, pipelines, and public transit facilities. The vulnerability of water infrastructure in the Sacramento Delta to seismic shaking was discussed. A public forum was held one evening of the conference to provide information to the general public in an accessible form. Numerous public agencies staffed information tables and provided information and educational materials on earthquake preparedness. Representatives from news i media, including a local television station, attended a press conference and portions of the technical sessions. The conference was coordinated with numerous other local activities held over a period of several months to raise public awareness of the 140th anniversary of the 1868 earthquake on the Hayward fault, and the high probability of another major earthquake on the fault in the near future. Field trips were conducted during the weekend following the conference to 1) the northern Hayward fault, 2) the southern Hayward fault, and 3) the stepover between the Hayward and Calaveras faults. A total of 44 people attended field trips. A one-day teacher training workshop on earthquake hazards held after the conference was attended by 19 teachers from local public schools. The workshop included lectures and demonstrations in the morning, and a field trip of the Hayward fault in the afternoon. The workshop included material on the new California science content standards related to plate tectonics and earthquakes. The conference was made possible through the generous efforts of many organizations and individuals. Online abstract submissions were managed by the Seismological Society of America. The conference website was provided by the California Geological Survey. Check-in, onsite registration desks and projection equipment were staffed by CSUEB students and staff. Pre-registration and credit card transactions were handled by campus bookstore staff, courtesy of Follett Higher Education Group. Vehicles and drivers for field trips were provided by CSUEB. The Incorporated Research Institutions for Seismology (IRIS) provided materials for the teachers workshop. The conference schedule, list of sponsors, and abstracts of presentations are included in the Conference Program with Abstracts immediately following this summary. A list of participants in the conference is provided at the end of the abstracts, followed by photographs of conference activities. A flier describing the teacher training workshop and a list of teacher participants are located at the end of the report. ii Contents Conference Program with Abstracts ……………………………………………………….....iv List of Sponsors ……….…………………………………………..…………………..1 Technical Program ...…………………………………………….………………..…...3 Abstracts (in alphabetical order by author last name) .................................................14 Conference Participant List ……………………………………………………………….. 116 Conference Photographs …………………………………………………………………....121 Teacher Training Workshop Announcement ……………………………………….………124 Teacher Training Workshop Participant List ………………………….……………………125 iii CONFERENCE PROGRAM WITH ABSTRACTS THIRD CONFERENCE ON EARTHQUAKE HAZARDS IN THE EASTERN SAN FRANCISCO BAY AREA SCIENCE, HAZARD, ENGINEERING AND RISK October 22-24, 2008 140th Anniversary of the 1868 Earthquake California State University East Bay Cover photos from the University of California Bancroft Library and the U.S. Library of Congress online archives. Introduction The Third Conference on Earthquake Hazards in the Eastern San Francisco Bay Area follows successful conferences held at California State University, East Bay in 1982 and 1992. The purpose of this conference is to synthesize and make public information on the earthquake science, hazard, engineering, and risk in the Eastern San Francisco Bay Area that has been developed since the 1992 conference. The activities and publications take advantage of interest in earthquake hazards and risk generated by the 140th anniversary of the 1868 Hayward fault earthquake (October 21).

  • New Empirical Relationships Among Magnitude, Rupture Length, Rupture Width, Rupture Area, and Surface Displacement
    Bulletin of the Seismological Society of America, Vol. 84, No. 4, pp. 974-1002, August 1994 New Empirical Relationships among Magnitude, Rupture Length, Rupture Width, Rupture Area, and Surface Displacement by Donald L. Wells and Kevin J. Coppersmith Abstract Source parameters for historical earthquakes worldwide are com­ piled to develop a series of empirical relationships among moment magnitude (M), surface rupture length, subsurface rupture length, downdip rupture width, rupture area, and maximum and average displacement per event. The resulting data base is a significant update of previous compilations and includes the ad­ ditional source parameters of seismic moment, moment magnitude, subsurface rupture length, downdip rupture width, and average surface displacement. Each source parameter is classified as reliable or unreliable, based on our evaluation of the accuracy of individual values. Only the reliable source parameters are used in the final analyses. In comparing source parameters, we note the fol­ lowing trends: (1) Generally, the length of rupture at the surface is equal to 75% of the subsurface rupture length; however, the ratio of surface rupture length to subsurface rupture length increases with magnitude; (2) the average surface dis­ placement per event is about one-half the maximum surface displacement per event; and (3) the average subsurface displacement on the fault plane is less than the maximum surface displacement but more than the average surface dis­ placement. Thus, for most earthquakes in this data base, slip on the fault plane at seismogenic depths is manifested by similar displacements at the surface. Log-linear regressions between earthquake magnitude and surface rupture length, subsurface rupture length, and rupture area are especially well correlated, show­ ing standard deviations of 0.25 to 0.35 magnitude units.

[1] The Hayward fault in the San Francisco Bay Area (SFBA) is sometimes considered unusual among continental faults for exhibiting significant aseismic creep during the interseismic phase of the seismic cycle while also generating sufficient elastic strain to produce major earthquakes. Imaging the spatial variation in interseismic fault creep on the Hayward fault is complicated because of the interseismic strain accumulation associated with nearby faults in the SFBA, where the relative motion between the Pacific plate and the Sierra block is partitioned across closely spaced subparallel faults.

    Bay Area Geophysical Society Seminar Series Thomas Brocher USGS November 19, 2018 4:00 PM McCone Hall 265, UC Berkeley The 150th Anniversary of the Damaging 1868 Hayward Earthquake: Why it Matters Abstract: October 21st marks the 150th anniversary of the damaging 1868 Hayward earthquake. USGS studies of the Hayward Fault reveal that it has produced 12 large earthquakes in the past 2000 years spaced from 100 to 220 years apart. The Hayward Fault is one of the most urbanized faults in the United States. So the expected large Hayward Fault earthquake will impact the entire San Francisco Bay Area. The odds of a damaging M6.7 earthquake in the San Francisco Bay Area in the next 30 years are nearly 3 out of 4. The effects of earthquakes can be mitigated through building codes, retrofits, planning, and training. Speaker Bio: Tom Brocher is a seismologist at the USGS Earthquake Science Center, in Menlo Park, where he has worked for 33 years after working briefly at the Hawaii Institute of Geophysics and Woods Hole Oceanographic Institution. He served as Director of the Earthquake Science Center for several years and prior to that served as the USGS Coordinator for Northern California Earthquake Hazard Investigations. His interests include earthquake hazard assessment, earthquake mitigation, and earthquake preparedness. Tom served as chair of the 1868 Hayward Earthquake Alliance, a public/private non-profit organization seeking to increase public awareness of that earthquake and the hazards posed by the Hayward Fault. Tom has authored or co-authored 165 peer-reviewed publications and is a Fellow of the Geological Society of America.

  • Final Report: USGS NEHRP Project G17AP00010
    Final Report: USGS NEHRP Project G17AP00010 Project Title: Automated fault mapping of the North America-Pacific plate boundary using airborne laser swath mapping (ALSM) data George Hilley and Robert Sare Department of Geological Sciences Stanford University Stanford, CA 94305-2115 email:[email protected] voice: (650) 723-3782 fax: (650) 725-0979 Term of Award: January 1, 2017-December 30, 2019 Abstract Fault scarps and fault-related landforms provide important information about fault zone ac- tivity over timescales that are not captured by instrumental measurements or historic records. Semi-automated methods for delineating these landforms using topographic data from light detection and ranging (lidar) and spaceborne imaging systems offer the opportunity to charac- terize fault zones on a global scale. This project explored a computationally efficient method for extracting scarp-like landforms from high-resolution (≤ 2 m), regional-scale (≥ 100-km-long) digital topographic datasets. We identified fault-related landforms using a curvature template based on the diffusion model for scarp degradation and extract scarp heights and morphologic ages at each pixel. The method was applied to the GeoEarthScope Northern California dataset, an airborne lidar acquisition imaging nearly 2500 km2 of the northern San Andreas fault sys- tem, by adapting the algorithm to use cloud computing resources. Template results and fault trace mapping show spatial agreement in active fault zones with clear topographic expression, including detection of fault scarps, shutter ridges, and elongated drainages. Comparison of the method against field-based morphologic dating of scarps along the southern San Andreas re- veals a trade-off between template window size and morphologic age contrasts resolved between strike-slip fault scarps of different relative ages.

GEOLOGICAL SURVEY Any use of trade names is for descriptive purposes only and does not imply endorsement by the Federal Government. INTRODUCTION The Western Earth Surface Processes Team (WESPT) of the U.S. Geological Survey (USGS) conducts geologic mapping, earth-surface processes investigations, and related topical earth science studies in the western United States. This work is focused on areas where modern geologic maps and associated earth-science data are needed to address key societal and environmental issues such as ground-water quality, landslides and other potential geologic hazards, and land-use decisions. Areas of primary emphasis in 2003 included southern California, the San Francisco Bay region, the Mojave Desert, the Colorado Plateau region of northern Arizona, and the Pacific Northwest. The team has its headquarters in Menlo Park, California, and maintains smaller field offices at several other locations in the western United States. The results of research conducted by the WESPT are released to the public as a variety of databases, maps, text reports, and abstracts, both through the internal publication system of the USGS and in diverse external publications such as scientific journals and books. This report lists publications of the WESPT released in 2003 as well as additional 2000, 2001, and 2002 publications that were not included in the previous lists (USGS Open-File Reports 00-215, 01-198, and 02-269).

  • Fault Scaling Relationships Depend on the Average Fault Slip Rate
    Manuscript Click here to download Manuscript RL+SR_2MW_r16.tex 1 Fault Scaling Relationships Depend on the 2 Average Fault Slip Rate 3 John G. Anderson, Glenn P. Biasi, Steven G. Wes- 4 nousky 5 Abstract 6 This study addresses whether knowing the slip rate on a fault improves es- 7 timates of magnitude (MW ) of shallow, continental surface-rupturing earth- 8 quakes. Based on 43 earthquakes from the database of Wells and Coppersmith 9 (1994), Anderson et al. (1996) previously suggested that estimates of MW from 10 rupture length (LE)areimprovedbyincorporatingthesliprateofthefault 11 (SF ). We re-evaluate this relationship with an expanded database of 80 events, 12 that includes 57 strike-slip, 12 reverse, and 11 normal faulting events. When the 13 data are subdivided by fault mechanism, magnitude predictions from rupture 14 length are improved for strike-slip faults when slip rate is included, but not for 15 reverse or normal faults. Whether or not the slip rate term is present, a linear 16 model with M log L over all rupture lengths implies that the stress drop W ⇠ E 17 depends on rupture length - an observation that is not supported by teleseismic 18 observations. We consider two other models, including one we prefer because it 19 has constant stress drop over the entire range of LE for any constant value of 20 SF and fits the data as well as the linear model. The dependence on slip rate for 21 strike-slip faults is a persistent feature of all considered models. The observed 22 dependence on SF supports the conclusion that for strike-slip faults of a given 23 length, the static stress drop, on average, tends to decrease as the fault slip rate 24 increases.
