Electronic Encyclopedia of Earthquakes @ University of Southern California
0085511 Henyey
The objective of this project is the creation of an Electronic Encyclopedia of Earthquakes (E3), which will function as an integral part of the NSF Digital Library Initiative. The lead organization in this project is the Southern California Earthquake Center (SCEC), in collaboration with California Universities for Research in Earthquake engineering (CUREE) and the Incorporated Research Institutes in Seismology (IRIS). The one-year pilot phase of this project will result in an operational framework with an initial set of entries; the enlargement of this collection is planned to then efficiently follow in a subsequent phase. The project name, Electronic Encyclopedia of Earthquakes, accurately describes the product of this project: The information will be electronic in form, communicated via the World Wide Web. Rather than only reading text, the user will be able to access data sets and to manipulate, visualize, and analyze the data in individualized ways. For example, the student or instructor will be able to select from a library of earthquake ground motion records and play a given record in combination with a structural model to experiment with the concept of dynamic response. The Electronic Encyclopedia of Earthquakes is related to a traditional printed encyclopedia in that it is entry-based, consisting of a series of topics, each dealt with as independent explanations and sets of information and yet also cross-referenced. The root meaning of "encyclopedia," the circle of knowledge, also applies, because the expanse of the topics will cover the earthquake subject in cross-disciplinary fashion. Earth sciences, engineering, physics, and mathematics are the four basic fields of knowledge to be included, with some treatment of impacts on human systems of earthquakes. Entries and data sets are provided that will allow the instructor or student to tie different topics together in an individualized, inquiry-based way, or to complete the circle, without encountering artificial divisions along traditional disciplinary lines. Thus, "encyclopedia" is an accurate description of this product, rather than "primer," because the goal here is to provide clearly organized, dynamic information that allows the learner to discover many different paths through the subject matter, or to create new knowledge, and not to meter out one idea or piece of information at a time in a pre-determined sequence. The third term, "earthquakes," is largely self-explanatory, except to note that E3 will not be limited to individual earthquakes, though specific major earthquakes will be included as entries and will be used to illustrate broader concepts. To balance the broad range and open-ended nature of the entries with the need for an instructor or student to quickly co-locate information found under different headings that is appropriate to their inquiry, threads of related content will be tagged and linked to provide continuity for a given likely level of user. For example, the content that will be mapped out to show high school teachers what may be useful for their physics courses is different than in the case of a college-level engineering or geophysics class where the same topic is treated in greater depth. The information will be layered in terms of its complexity or implied prerequisite knowledge: A primary (glossary), secondary (precis), and tertiary (in-depth information) framework will be used. A large amount of information exists in this field that can be adapted for this collection, but a common problem is that the Web user often encounters a large volume of low quality or irrelevant data in the process of eventually finding the content they desire. The layered framework and the encyclopedic idea of cross-references, along with a commitment to quality control to ensure high academic standards, have been designed to overcome this problem.

Itr/Ap: the Scec Community Modeling Environment: An Information Infrastructure For System-Level Earthquake Research @ University of Southern California
0122464 Jordan
It is now possible, because of recent advances in geophysics, to create for the first time, fully three-dimensional simulations of earthquake fault-rupture and fault-system dynamics. Such physics-based simulations are crucial to gaining a fundamental understanding of earthquake phenomena, and they can potentially provide enormous practical benefits for assessing and mitigating earthquake risks through improvements in seismic hazard analysis. The Southern California Earthquake Center (SCEC) has embarked on an ambitious program to develop physics-based models of earthquake processes and integrate these models into a new scientific framework for seismic hazard analysis and risk management. This project involves a collaboration among SCEC, the Information Sciences Institute (ISI), the San Diego Supercomputer Center (SDSC), the Incorporated Institutions for Seismology (IRIS), and the U.S. Geological Survey (USGS) to develop a "Community Modeling Environment", which will function as a virtual collaboratory for the purposes of knowledge quantification and synthesis, hypothesis formulation and testing, data assimilation and conciliation, and prediction.
To achieve its objectives, the environment must provide a means for describing, configuring, initiating, and executing complex computational pathways that result from the composition of various earthquake simulation models. This entails solving a number of challenging problems in information technology. To solve these problems, the principal investigators will draw on several distinct computer science disciplines: 1) Knowledge representation and reasoning techniques; 2) Grid technologies; 3) Digital library technology; and 4) Interactive knowledge acquisition techniques.
A central element of this project will be a Knowledge Transfer, Education and Outreach program with four primary goals: 1) to transfer the technology developed under this project to the end users of earthquake information, including engineers, emergency managers, decision makers, and the general public; 2) to cross-educate advanced students in the fields of geoscience and computer-science; 3) to make the general public aware of the benefits of applying advanced information technology to the problems of earthquake risk; and 4) to use public interest in earthquake information to attract beginning students into geoscience and computer science. A specific objective will be to engage young Hispanic Americans in the intellectual challenges of earthquake information technology. ***

Monitoring An Active Rift System At the Front of Amery Ice Shelf, East Antarctica @ University of California-San Diego Scripps Inst of Oceanography
This award supports a comprehensive study of rift growth on the Amery Ice Shelf (AIS), East Antarctica, using a combination of in situ and remote sensing data with numerical modeling. On the AIS there is an opportunity to examine an active rift system, which is a combination of two longitudinal-to-flow rifts, which originated at the ice shelf front in the suture zones between merging flowbands, and two transverse-to-flow rifts, which formed at the tip of the western longitudinal rift around 1996. Work in progress indicates that these two transverse rifts do not propagate independently of each other, but somehow grow more or less synchronously. The longest of these rifts-the eastern one-grows at an average rate of about 8m per day. When it meets the eastern longitudinal rift, an event that is expected to occur during the funding period (mid-2006), an iceberg (~30 x 30 km) will calve. Based on observations collected over the past half century, there is reason to believe that such a calving event may be a part of a repetitive sequence. In the proposed project, the expansion and propagation of both transverse rifts will be studied using a network of GPS and seismometers deployed around the tip of each transverse rift. Once the iceberg has calved, the effects its calving has on the dynamics of the ice shelf and the activation of previously inactive rifts will also be studied. Insofar as the rate of calving activity is a proxy for local and regional climate conditions, a broader impact of the proposed work is directly related to the socio-environmental topics of climate and sea-level change. The subject of iceberg calving has a history of sparking a great deal of interest from the media and the public alike, especially since the recent large calving events from the Ross and Ronne ice shelves and the remarkably sudden break-up of the Larsen Ice Shelf. The work will involve at least one graduate student, and will involve a partnership with a local charter high school. Field work, instrument deployments, and data collection and analysis will be conducted in close collaboration with the Australian Antarctic Division and the University of Tasmania, which has been a crucial component of research conducted to date. This project will also make use of the Scripps Institution of Oceanography Visualization Center as a means to display results to faculty and researchers of the University of California, San Diego, undergraduate and graduate students, to school children and their teachers, and ultimately to the visiting public.

A Petascale Cyberfacility For Physics-Based Seismic Hazard Analysis @ University of Southern California
This CME Collaboration proposes to transform probabilistic seismic hazard analysis (PSHA) into a physics-based science by deploying a new cyberfacility "PetaSHA" that can execute PSHA computational pathways and manage data volumes using the nation's petascale computing resources. The objectives of the project have been formulated in terms of three science thrusts: (1) Extend deterministic simulations of strong ground motions to 3 Hz for investigating the upper frequency limit of deterministic ground-motion prediction. (2) Improve the resolution of dynamic rupture simulations by an order of magnitude for investigating the effects of realistic friction laws, geologic heterogeneity, and near-fault stress states on seismic radiation. (3) Compute physics-based PSHA maps and validate them using seismic and paleoseismic data. The investigators will assemble and operate a cyberfacility comprising four computational platforms, each designed to execute and manage the results from specific PSHA computational pathways. Two of these platforms, OpenSHA and TeraShake, have been developed by the CME Project. PetaShake will be an advanced research platform for petascale simulations of dynamic ruptures and ground motions with petascale capability computing and will be able to archive complete simulation data volumes (petascale data-intensive computing). CyberShake will be a new production platform that will employ advanced workflow management tools to compute and store the large suites of ground motion simulations needed for physics-based PSHA mapping. They will move these computational platforms forward in complexity and scale through a graduated series of calculations tied to a timeline with clear measures of success and will also develop a set of science gateways for the broader community, in particular researchers involved in the EarthScope and NEES Projects, to provide access to PSHA simulation capabilities and data products. The objectives include the cross-training of diverse groups of undergraduate interns and early-career scientists that will enable them to solve fundamental problems.

Collaborative Research: 3-D Near-Field Coseismic Deformation From Differential Lidar With Application to the El Mayor-Cucapah Earthquake @ University of California-San Diego Scripps Inst of Oceanography
One of the most powerful applications of fault-zone LiDAR scans is to serve as the before image for comparison with a survey acquired after a future surface-rupturing earthquake. Then, every displaced feature acts as a geodetic marker from which an ultra-high resolution map of the surface displacement field may be constructed. Such a detailed displacement field shows how faults and their containing rock volume act together to accommodate deformation and grow geologic structures over successive earthquakes. This provides new understanding of how earthquake ruptures connect faults to generate larger, more destructive events, and illuminates cryptic, distributed components of deformation needed for improving estimates of long-term deformation rates and seismic hazard. This grant through the NSF EarthScope Program and the Americas Program of the NSF Office of International Science and Engineering supports the development of fully 3-dimensional approaches to unraveling deformation from successive airborne LiDAR scans of a fault zone. The focus of the project is the before and after airborne lidar scans of the April 4, 2010 El Mayor-Cucapah (EMC) earthquake rupture in northern Baja California, Mexco. The project objectives address three challenges in working with this data set: (1) reprocessing of the pre-earthquake data to reduce scanning artifacts and improve accuracy; (2) development of methods for rigorous, high-resolution displacement measures from point-cloud data of vastly different resolutions (9 to 18 pts/m2 post-earthquake compared with 0.013 pts/m2 pre-earthquake); (3) preliminary 3-D mechanical modeling of fault-zone deformation from this event. Meeting these challenges will advances knowledge of fault-zone deformation gained from this earthquake, as well as advance techniques for analysis of the next earthquake captured by differential LiDAR -- quite possibly along one of the numerous active faults imaged as part of the Earthscope facility.
Coseismic surface rupture is an important, accessible record of earthquake slip, and the primary record of prehistoric seismicity. Near-field deformation measurements from differential LiDAR can transform our understanding of how coseismic surface ruptures are produced and distributed within fault zones. New knowledge to be gained includes understanding the mechanical coupling of fault slip to near-field distributed deformation, quantifying distributed components of fault slip otherwise difficult to measure, and predicting the style, extent, and magnitude of high strains around fault zones that could damage buildings and critical infrastructure. The techniques developed for this project will also prove valuable for other applications, such as in geomorphology, civil engineering, and robotics. This research brings together the expertise from five U.S.-based research groups that are leaders in the study of differential airborne LiDAR: UC Davis, Arizona State, UC San Diego, University of Houston, and Caltech / USGS. This project also broadens international collaborations formed following the EMC earthquake by involving researchers and students from CICESE, Baja California, in the development and deployment of new differential LiDAR algorithms and the open-source LiDAR-visualization software.
