Download or read book A Top down Hierarchical Approach to the Display and Analysis of Seismic Data written by Christopher J. Young and published by . This book was released on 1995 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seismic monitoring of a CTBT (Comprehensive Test Ban Treaty) will require analysts to review tens of events per hour recorded by networks of more than a hundred stations. Use of the traditional waveform display as the primary data display tool is incompatible with this requirement; traditional waveform displays are inefficient in their presentation of relevant data and place high demands on computer resources. Drawing on resident data visualization expertise and on our hands-on experience with the design and implementation of the ADSN (AFTAC Distributed Subsurface Network) system at AFTAC, we have designed a new system consisting of a hierarchical series of displays which present relevant information to the analyst in a more efficient manner. The displays are designed to be used in a top-down manner with the analyst starting with the most general display and proceeding to the most specific (the waveform display) only when it is needed. Testing to date has focussed on data from the GSETT2 (Group of Scientific Experts Technical Test #2) in 1991. Future efforts will be directed towards improved data sets from the ongoing GSETT3.

Download or read book Statistical Evaluation of CTBT Regional Seismic Monitoring written by and published by . This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A global seismic monitoring system under a Comprehensive Test Ban Treaty (CTBT) is judged by its capability to detect, locate, and identify suspicious seismic events. Performance measures are those statistical objects that describe these capabilities. Performance criteria are the thresholds derived from the overall monitoring system goals, against which the evaluated performance measures are compared. This report proposes statistical objects for performance measurement of detection and location, a continuation of the research of Anderson and Anderson. A statistical methodology for calibrating regional station magnitudes to the worldwide teleseismic Mb scale is also proposed.

Download or read book An Overview of Seismic Discrimination Issues Relevant to CTBT Monitoring written by J. R. Murphy and published by . This book was released on 1995 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Conference on Disarmament of the U.N. General Assembly is currently working to draft a Comprehensive Test Ban Treaty (CTBT) which will prohibit all nuclear testing. Because seismology remains as the primary monitoring technique for verifying treaty compliance with respect to underground nuclear tests, it is appropriate at this time to once again review the current state of understanding regarding the seismic identification of such explosions. It is evident that no practical seismic monitoring system will ever insure identification of all conceivable underground nuclear tests and, therefore, it is important to begin any such assessment of capability by recognizing that it is first necessary to establish a monitoring threshold goal, which will ultimately represent some compromise between system cost and various political and military considerations.

Download or read book DOE Program on Seismic Characterization for Regions of Interest to CTBT Monitoring written by and published by . This book was released on 1995 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary goal of the DOE programs on Geophysical Characterization of (1) the Middle East and North Africa (ME-NA) and (2) Southern Asia (SA) is to provide the Air Force Technical Applications Center (AFRAC) with the analytic tools and knowledge base to permit effective verification of Comprehensive Test Ban Treaty (CTBT) compliance in those regions. The program also aims at using these regionalizations as models for the development of a detailed prescription for seismic calibration and knowledge base compilation in areas where the US has had little or no previous monitoring experience. In any given region, the CTBT seismic monitoring system will depend heavily on a few key arrays and/or three-component stations, and it will be important to know as much as possible about the physical properties of the earth's crust and upper mantle: (1) in the vicinity of these stations, (2) in areas of potential earthquake activity or commercial blasting in the region containing the stations, and (3) along the propagation path from the sources to the stations. To be able to discriminate between various source types, we will also need to know how well the various event characterization techniques perform when they are transported from one tectonic or geologic environment to another. The Department of Energy's CMT R & D program plan (DOE, 1994), which includes the ME-NA and SA characterization programs, incorporates an iterative process that combines field experiments, computer modeling and data analysis for the development, testing, evaluation and modification of data processing algorithms as appropriate to achieve specific US monitoring objectives. This process will be applied to seismic event detection, location and identification.

This book was released on 1997-08-01 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: On September 24, 1996, President Clinton signed the Comprehensive Nuclear Test Ban Treaty at the United Nations Headquarters. Over the next five months, 141 nations, including the four other nuclear weapon statesâ€"Russia, China, France, and the United Kingdomâ€"added their signatures to this total ban on nuclear explosions. To help achieve verification of compliance with its provisions, the treaty specifies an extensive International Monitoring System of seismic, hydroacoustic, infrasonic, and radionuclide sensors. This volume identifies specific research activities that will be needed if the United States is to effectively monitor compliance with the treaty provisions.

Book excerpt: The past few decades have witnessed the growth of the Earth Sciences in the pursuit of knowledge and understanding of the planet that we live on. This development addresses the challenging endeavor to enrich human lives with the bounties of Nature as well as to preserve the planet for the generations to come. Solid Earth Geophysics aspires to define and quantify the internal structure and processes of the Earth in terms of the principles of physics and forms the intrinsic framework, which other allied disciplines utilize for more specific investigations. The first edition of the Encyclopedia of Solid Earth Geophysics was published in 1989 by Van Nostrand Reinhold publishing company. More than two decades later, this new volume, edited by Prof. Harsh K. Gupta, represents a thoroughly revised and expanded reference work. It brings together more than 200 articles covering established and new concepts of Geophysics across the various sub-disciplines such as Gravity, Geodesy, Geomagnetism, Seismology, Seismics, Deep Earth Processes, Plate Tectonics, Thermal Domains, Computational Methods, etc. in a systematic and consistent format and standard. It is an authoritative and current reference source with extraordinary width of scope. It draws its unique strength from the expert contributions of editors and authors across the globe. It is designed to serve as a valuable and cherished source of information for current and future generations of professionals.

Download or read book Statistical Framework for Event Identification and Assessment of Seismic CTBT Monitoring Capability written by Mark D. Fisk and published by . This book was released on 1995 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: This effort focuses on several main areas regarding event identification within the context of CTBT monitoring: (1) development and integration at the Center for Monitoring Research (CMR) of a software system for event characterization/identification; (2) assessment of regional seismic event identification performance; (3) analysis of GSETT-3 Alpha network data to assess the availability and utility of event characterization parameters for global monitoring; and (4) investigation of robust multi-sensor data fusion techniques for outlier detection and event classification. We have been implementing a statistical event identification framework. The fundamental methods consist of statistical tests for outlier detection and event classification, as well as algorithms to test appropriate assumptions regarding the data in order to optimize and ensure validity of the results. Our methodology: (1) accurately treats statistical uncertainties of all discriminants used; (2) provides flexibility to incorporate any discriminant and assess its utility objectively; (3) can identify nuclear tests in regions for which relevant ground-truth training data may or may not exist; (4) can function in an automated mode to flag, categorize and/or rank anomalous events; (5) can control the false alarm rate; (6) and provides a rigorous and defensible framework with which to report and justify the results. To also serve as an interactive analysis tool, we have been developing an X Window graphical user interface, featuring a wide range of displays and exploratory data analysis tools. We have applied the methods to seismic events recorded by the ARCESS and GERESS arrays, station WMQ in China, and stations KNB and MNV in the western U.S.
