Book excerpt: This report is in three sections: Section one describes empirical estimates of yield and tectonic release for 71 underground nuclear explosions conducted at the Shagan River Test Site, Kazakhstan, from 1977 to 1989. The method is based upon teleseismic observations of fundamental mode Love and Rayleigh waves at stations of the GDSN, CDSN, RSTN, and IRIS/USGS GSN. In 1977 as few as five stations were providing data, while in the late 1980's more than 25 stations were operational. Section two makes a case for generating lists of problems events - seismic sources whose signals cannot easily be discriminated - as a mechanism for achieving three goals: (1) encouraging seismologists to contribute data that may help to discriminate events listed; (2) training; and (3) helping to build consensus in the technical community, on what types of problem events are truly intractable with current data Section three describes spectral-temporal characteristics of regional seismograms and shows how they can be used to discriminate between different types of seismic sources. We analyze the high-frequency (1-40 hz) spectral of chemical explosions and earthquakes at local and regional distances to understand the seismic signal characteristics of different types of sources and to find stable discriminators. We evaluate the application of the spectrogram technique to regional seismograms in different geologic settings using data from single explosions, multiple-hole instantaneous explosions, ripple-fired quarry blasts, and earthquakes. The effects on high frequency spectra of local source and recorder site conditions and source to receiver path are also analyzed.

This book was released on 1995 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this report we describe some results of investigations on a problem of discrimination between nuclear explosions, chemical explosions and earthquakes, carried out in the Complex Seismological Expedition of the Joint Institute of Physics of the Earth of the Russian Academy of Sciences. Records of underground nuclear explosions from the Semipalatinsk test site, and from region the Pre-Caspian depression, and also records of nearby chemical explosions and earthquakes were processed. We analysed records of permanent and temporary stations, located mainly in the North Tien Shan, northern Kazakhstan and Urals regions. We studied the influence of regional conditions on the effectiveness of seismic monitoring of nuclear explosions. Various amplitude criteria of the discrimination between explosions and earthquakes are considered. We analyzed possibilities to discriminate different source types using spectral-temporal characteristics of seismograms. The nature of some wave types, recorded at region distances, is investigated. We consider possibilities of discrimination between nuclear and chemical explosions and earthquakes using analysis of characteristics of irregular waves. We outline future investigations, connected with the study of the unique set of seismograms kept in the CSE.

Book Synopsis Explosion and Earthquake Source Discrimination by : Brian W. Stump
Download or read book Explosion and Earthquake Source Discrimination written by Brian W. Stump and published by . This book was released on 1982 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes work accomplished by the Air Force Weapons Laboratory during the period May 1981 to April 1982. The purpose of this work has been to focus on seismic source characterizations of explosive sources. Specifically, we have investigated the usefulness of the moment tensor representation in modeling near-field recordings of contained nuclear explosions. Extension of the source representation to surface explosions utilizing the zeroth order moment has also been accomplished. In an attempt to investigate the possibility of using small scale high-explosive tests in studying source characterization problems, a 256-pound fully contained chemical explosion was instrumented and detonated. A preliminary data report. is included while data analysis is ongoing. Further studies of small scale surface and buried chemical explosions are outlined in. Reflectivity modeling of the observational data was attempted.

This book was released on 2001-12-01 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pure appl. geophys., by 161 nations. Entry of the treaty into force, however, is still uncertain since it requires ratification by all 44 nations that have some nuclear capability and, as of 15 June 2001, only 31 of those nations have done so. Although entry of the CTBT into force is still uncertain, seismologists and scientists in related fields, such as radionuclides, have proceeded with new research on issues relevant to monitoring compliance with it. Results of much of that research may be used by the International Monitoring System, headquartered in Vienna, and by several national centers and individual institutions, to monitor compliance with the CTBT. New issues associated with CTBT monitoring in the 21st century have presented scientists with many new challenges. They must be able to effectively monitor com pliance by several countries that have not previously been nuclear powers. Effective monitoring requires that we be able to detect and locate much smaller nuclear events than ever before and to distinguish them from small earthquakes and other types of explosions. We must have those capabilities in regions that are seismically active and geologically complex, and where seismic waves might not propagate efficiently.

Book Synopsis Geophysics in the Affairs of Man by : Charles C. Bates
Download or read book Geophysics in the Affairs of Man written by Charles C. Bates and published by Elsevier. This book was released on 2016-01-22 with total page 567 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geophysics in the Affairs of Man describes how geophysics has affected human affairs, with emphasis on the geophysical enterprise as an interplay of technical, social, and economic factors. Many of the key and intriguing developments that took place within several major fields of geophysics are divided into seven epochs, roughly broken into decades. Topics covered include the origins of the profession of geophysics, earth physics and oceanography, and geophysical aspects of undersea warfare. This book is comprised of nine chapters and begins with a discussion on some antecedents to the modern-day profession of geophysics through World War I. The following chapters focus on the golden days of exploration geophysics; classical seismology during the war years; the growth of geophysics during the 1950s; and the nature of the geophysical exploration industry. The closing chapter presents the views of numerous geophysicists about what they consider the most outstanding actions they were ever involved in, as well as what makes the profession unique. This monograph is written primarily for geophysicists, geologists, and geological engineers.
