  • STRUCTURAL GEOLOGY and TECTONICS DIVISION Newsletter Volume 13, Number 1 March 1994
    STRUCTURAL GEOLOGY and TECTONICS DIVISION Newsletter Volume 13, Number 1 March 1994 CHAIRPERSON'S MESSAGE Division activities at the annual meeting in Boston were quite successful. John Bartley became the new second vice chair, Ed Beutner moved up to first vice-chair and Art Goldstein is the new secretary-treasurer. We all thank the past secretary-treasurer, Don Secor, for keeping the Division running properly during his record tenure of six years. The papers at Division sessions were excellent, so interesting to me that I spent the meeting in these sessions and missed the exhibits. Thanks to Fred Chester and Ron Bruhn for organizing a really cutting-edge symposium on inferring paleoearthquakes from fault-rock fabrics. It appears that this seemingly intractable problem has some solutions. We can expect some significant publications from the speakers. Terry Engelder, with help from Mike Gross and Mark Fischer presented the Division's short course on fracture mechanics of rock. The course was highly praised by everyone I heard from; thanks guys. As always, it was a pleasure to attend the Division's award ceremony to honor the recipients and to hear the citations and responses. As Darrel Cowan, in his citation of Ben Page for the Career Contribution Award, summarized Ben's significant publications, I was intrigued as I realized that my list would have been as long but different. Such a broad range of important contributions is an excellent qualification for this award. Mark Cloos cited Dan Worrall and Sig Snelson for the best paper award for their 1989 DNAG paper "Evolution of the northern Gulf of Mexico, with emphasis on Cenozoic growth faulting and the role of salt." This paper contains important new insights into regional salt tectonics as well as helps highlight a large region of very active tectonics that misses out on being a classic orogenic belt only because it is not forming mountains.

  • 3-8 Geologic-Seismic
    Environmental Evaluation 3-8 GEOLOGIC-SEISMIC Changes Since the Draft EIS/EIR Subsequent to the release of the Draft EIS/EIR in April 2004, the Gold Line Phase II project has undergone several updates: Name Change: To avoid confusion expressed about the terminology used in the Draft EIS/EIR (e.g., Phase I; Phase II, Segments 1 and 2), the proposed project is referred to in the Final EIS/EIR as the Gold Line Foothill Extension. Selection of a Locally Preferred Alternative and Updated Project Definition: Following the release of the Draft EIS/EIR, the public comment period, and input from the cities along the alignment, the Construction Authority Board approved a Locally Preferred Alternative (LPA) in August 2004. This LPA included the Triple Track Alternative (2 LRT and 1 freight track) that was defined and evaluated in the Draft EIS/EIR, a station in each city, and the location of the Maintenance and Operations Facility. Segment 1 was changed to extend eastward to Azusa. A Project Definition Report (PDR) was prepared to define refined station and parking lot locations, grade crossings and two rail grade separations, and traction power substation locations. The Final EIS/EIR and engineering work that support the Final EIS/EIR are based on the project as identified in the Final PDR (March 2005), with the following modifications. Following the PDR, the Construction Authority Board approved a Revised LPA in June 2005. Between March and August 2005, station options in Arcadia and Claremont were added. Changes in the Discussions: To make the Final EIS/EIR more reader-friendly, the following format and text changes have been made: Discussion of a Transportation Systems Management (TSM) Alternative has been deleted since the LPA decision in August 2004 eliminated it as a potential preferred alternative.

  • Iv.E Geology
    IV.E GEOLOGY 1.0 INTRODUCTION This section of the Draft Environmental Impact Report (EIR) identifies and evaluates geologic and soils conditions at Loyola Marymount University (LMU) campus that could affect, or be affected by, implementation of the Proposed Project. The information contained in this section is based on a geotechnical evaluation1 prepared by MACTEC Engineering and Consulting, Inc., (MACTEC) prepared in July 2009, which is provided in Appendix IV.E. 2.0 REGULATORY FRAMEWORK 2.1 State and Regional Regulations 2.1.1 Seismic Hazards Mapping Act Under the Seismic Hazards Mapping Act of 1990, the State Geologist is responsible for identifying and mapping seismic hazards zones as part of the California Geological Survey. The Geological Survey provides zoning maps of non-surface rupture earthquake hazards (including liquefaction and seismically induced landslides) to local governments for planning purposes. These maps are intended to protect the public from the risks involved with strong ground shaking, liquefaction, landslides or other ground failure, and other hazards caused by earthquakes. For projects within seismic hazard zones, the Seismic Hazards Mapping Act requires developers to conduct geological investigations and incorporate appropriate mitigation measures into project designs before building permits are issued. Most of the Southern California region has been mapped. Established by the Seismic Safety Commission Act in 1975, the State Seismic Safety Commission’s purpose is to provide oversight, review, and recommendations to the Governor and State Legislature regarding seismic issues. 2.1.2 Alquist-Priolo Earthquake Fault Zoning Act The Alquist-Priolo Earthquake Fault Zoning Act (the Act) (Public Resource Code Section 2621.5) of 1972 was enacted in response to the 1971 San Fernando earthquake, which caused extensive surface fault ruptures that damaged numerous homes, commercial buildings, and other structures.

  • Quaternary Fault and Fold Database of the United States
    Jump to Navigation Quaternary Fault and Fold Database of the United States As of January 12, 2017, the USGS maintains a limited number of metadata fields that characterize the Quaternary faults and folds of the United States. For the most up-to-date information, please refer to the interactive fault map. Lower Elysian Park thrust (Class A) No. 134 Last Review Date: 2017-06-14 citation for this record: Bryant, W.A., compiler, 2017, Fault number 134, Lower Elysian Park thrust, in Quaternary fault and fold database of the United States: U.S. Geological Survey website, https://earthquakes.usgs.gov/hazards/qfaults, accessed 12/14/2020 02:13 PM. Synopsis Davis and others (1989) interpret the Elysian Park anticlinorium to be formed by stacked fault propagation folds; Elysian Park thrust is the lower ramp. The thrust propagates upward from an assumed detachment at about 15 km to a depth of about 10 km. Shaw and Suppe (1996) prefer a fault-bend fold model that links the Elysian Park fault ramp with the Compton [133] ramp to the west. This is implied by the similar kink band widths (growth triangles) associated with the two ramps. They define two segments of the Elysian Park Thrust (Los Angeles and Whittier) that are offset in the vicinity of the Whittier Narrows earthquake. Schneider and others (1996) define the Los Angeles fault as that responsible for ongoing deformation of the south facing monocline that forms the northern Los Angeles shelf, based on structural reconstruction from well log data and seismic stratigraphy. In well logs they recognize increasing dip with depth, suggesting that fold growth has been by progressive limb rotation.

  • Simulating Earthquake Damage to the Electric-Power Infrastructure: a Case Study for Urban Planning and Policy Development
    Simulating Earthquake Damage to the Electric-Power Infrastructure: A Case Study for Urban Planning and Policy Development L. Jonathan Dowell Sudha Maheshwari Los Alamos National Laboratory Urban Planning and Policy Development P. O. Box 1663 MS F604 Rutgers University Los Alamos, NM 87545 New Brunswick, NJ 08901 [email protected] [email protected] (505) 665-9193 FAX (505) 665-5125 Abstract This paper presents a case study of the consequences of a Richter magnitude 6.75 earthquake on the Los Angeles Elysian Park fault to the electric-power infrastructure of the western United States. The analysis combines aspects of geological modeling of such an earthquake with probabilistic simulation of power-system component failures for evaluation of the operation of the engineering infrastructure. This hybrid analysis demonstrates emergent behavior of a complex system and illustrates the challenges of multi-disciplinary analyses necessary for computational operations research. The simulation predicts blackouts in the Los Angeles metropolitan area and abnormal voltages throughout the western U.S. electric-power infrastructure that compare favorably with the consequences observed following a recent Northridge earthquake. The paper discusses applications of such analyses for urban planning and policy development. 1. INTRODUCTION Assessment of the possible consequences of a major natural disaster is a daunting problem. This paper presents an approach to the assessment of the implications of a moderate earthquake in the Los Angeles basin to the electric- power infrastructure of the western United States. Such assessment requires evaluation of a complex system of systems, requiring expert knowledge of the operation and behavior of each system, the interactions between these systems.

    Subsurface Evidence for the Puente Hills and Compton-Los Alamitos Faults in South-Central Los Angeles 2010 SCEC Annual Report Project # 10066 Robert S. Yeats and Danielle Verdugo Earth Consultants International 1642 E. 4th Street, Santa Ana, CA 92701 Abstract We analyzed well data in the vicinity of a deep exploration campaign in 1973-1975 by American Petrofina Exploration Co. to a maximum depth of 6,477 m (American Petrofina Core Hole 1), twice the depth of data from multichannel seismic profiles used in previous studies. The deeper control of the Compton-Los Alamitos (CLA) and Puente Hills reverse faults based on these wells provides evidence of reverse faulting based on repetition of strata on electric logs, abrupt changes of dipmeter-based attitudes, and offset of events on seismic profiles following Avalon Boulevard and Vermont Avenue. Structure contours on the Puente Hills fault are straightforward, whereas contours on the CLA fault are more complex. The presence of faulting at depth leads to the conclusion that the CLA and Puente Hills reverse faults change upward into fault-propagation folds rather than fault-bend folds. The CLA fault marks the northeastern boundary of a broad anticline, called here the Central Uplift anticline, cut along its crest by the right-lateral strike-slip Potrero fault in the vicinity of our study. Structure contours at depth confirm the observations of others that the CLA fault swings westward and steepens in dip toward the NIFZ south of Inglewood oil field. The presence of reverse- fault-plane solutions along the northern NIFZ and evidence for uplift along the CLA fault east of Long Beach and Seal Beach oil fields during the 1933 Long Beach earthquake support an interpretation of faulting along the Newport- Inglewood trend related to strain partitioning, indicating that the NIFZ might generate a Coalinga-type reverse fault as well as a strike-slip event similar to the 1933 earthquake.

Southern California, specifically Orange County, is where I grew up and throughout the years, I have witnessed concrete lots and open spaces transform into shopping malls, car dealerships, housing tracts and small parks throughout the county. To visitors and those not native to Orange County, the notion that a natural environment still exists is very unlikely. However, when I was in third grade, I had the unique opportunity to visit an estuary called the Upper Newport Back Bay Nature Reserve located in Newport Beach. I learned the importance of tide habitats for plants and animals, how humans created endangered species, and several ways we could help save the Earth. It was a memorable field trip because it was my first hands-on experience in a delicate habitat, and even in my third grade mindset, I began to be more aware of how human actions affect the Earth.

Summary This past year, we made significant progress in improving SCEC’s Community Fault Model (CFM) and enhancing the recently developed website and associated database that allows users to access and query the model and its associated metadata. The CFM (Plesch et al., 2007) is one of SCEC’s most established and widely used community resources, with applications in many aspects of SCEC science, including crustal deformation modeling, wave propagation simulations, and probabilistic seismic hazards assessment (e.g., UCERF3). The CFM also directly contributes to other community modeling efforts, such as the Geological Framework (GFM), Community Rheologic (CRM), and Community Velocity (CVM-H) Models. This project represents a collaboration between the SCEC CXM co-chair (Marshall), Associate Director for IT (Maechling), CXM software developer (Mei-Hui Su), and the primary Community Fault Model (CFM) developers (Plesch and Shaw).
