Available in PDF, EPUB and Kindle. Book excerpt: There is a considerable body of data, including all the direct P-Wave data from Project Cowboy, which indicates a decoupling factor of the order of two for a salt cavity compared to tamped alluvium or valley tuff. Cavities in soft rock probably do not decouple at all but increase the seismic signal. An increase in decoupling due to high frequency absorption appears unlikely, but should such an effect exist, decoupling factors would probably still be less than ten. Cavity decoupling may actually increase detectability because of the lower background noise at the higher frequencies produced by the cavity. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Decoupling explosive energy by detonating charges in cavities larger than the charge is an effective method for reducing ground shock magnitudes over those of fully contained bursts. The report presents an analysis of ground motions generated by decoupled explosions in rock cavities. A simplified elastic solution is used to calculate particle motion magnitudes and time histories produced by an explosion in rock as a function of the initial cavity radius and the loading density of the explosive. Loading density is defined as the total explosive weight divided by the initial cavity volume. (Modified author abstract).

Available in PDF, EPUB and Kindle. Book excerpt: A discussion is presented concerning the implications of, and questions raised by, the cowboy underground detonations with chemical explosives. These experiments verified the correctness of the theory that explosions in a large cavity experience a decoupling effect, that is, the resulting seismic signals are muffled. The Cowboy tests left certain problems still to be solved (e.g., the relationship between cavity volume and depth and the decoupling factor, and the possibility that chemical explosions produce significantly different curves from nuclear explosions under the test conditions).

This book was released on 2012-12-06 with total page 843 pages. Available in PDF, EPUB and Kindle. Book excerpt: An international treaty banning the testing of any nuclear device in any environment - a comprehensive test ban treaty (CTBT) - has been on the political agenda for nearly 40 years. Objections to a CTBT have been political, technical, or a combination of both. However, the possibilities seem better after the end of the Cold War. In the prevailing, cooperative disarmament climate a CTBT appears likely to be approved by most countries in 1996. Hence the great current interest in monitoring technologies and capabilities. Such issues are comprehensively addressed here, a preamble being devoted to the political developments and setbacks over the past 40 years. Since seismic means are considered the dominant monitoring element, they are explored in detail. Contributions cover network deployments, advanced signal processing, wave propagation in heterogeneous media, and seismic source representations, and a variety of techniques for source classification (including neural networks). Complementary monitoring techniques, such as hydroacoustics, radionuclides and infrasound, are also summarised. The IAEA operation for monitoring compliance with the Non-Proliferation Treaty is also presented. The book also includes eyewitness accounts of the Soviet 50 Mt megabomb development and test, as well as the efforts made by the state to monitor the nuclear test programmes of the western powers. Includes some 33 articles written by distinguished scientists active in CTBT monitoring research for decades.

Available in PDF, EPUB and Kindle. Book excerpt: Monitoring Underground Nuclear Explosions focuses on the checking of underground nuclear explosions, including the Comprehensive Test Ban Treaty (CTB), seismological stations, earthquake-source models, and seismicity. The publication first elaborates on test-ban negotiations, nuclear explosions, seismological background, and explosions and earthquakes as seismic sources. Concerns cover comparison between explosion-source and earthquake-source models, theoretical calculation of seismic waves, earth structure, seismicity, nuclear test activities, bomb designs, and disarmament treaties. The manuscript then tackles seismological stations, detection, event definition and location, depth estimation, and identification. Topics include multistation discriminants, statistical aspects, long-period and short-period signals, near distances, location by a network of stations, international data exchange, station detection capabilities, and station networks. The book examines the monitoring of a comprehensive test-ban treaty, nonseismological identification, evasion, peaceful nuclear explosions, and yield estimation. The text is a dependable reference for researchers interested in the monitoring of underground nuclear explosions.

Book excerpt: The Cowboy experiments on decoupling of underground nuclear explosions show that the principle of decoupling by means of a large hole is correct. The decoupling factor of 300 estimated in RAND Report R-348 is still the best estimate for a hole in salt relative to a tamped shot in Nevada tuff. It was found that decoupling is not an all or none effect and that, if the elastic limit of the medium is exceeded, the decoupling factor is reduced, but only gradually. As a result it appears possible to explode a 20-kt device in a cavity no bigger than some which already exist, without prcducing a signal that could be detected by the Geneva system. (auth).

Available in PDF, EPUB and Kindle. Book excerpt: In December 2016, the Bulletin of Atomic Scientists moved their iconic “Doomsday Clock” thirty seconds forward to two and a half minutes to midnight, the latest it has been set since 1952, the year of the first United States hydrogen bomb test. But a group of scientists—geologists, engineers, and physicists—has been fighting to turn back the clock. Since the dawn of the Cold War, they have advocated a halt to nuclear testing, their work culminating in the Comprehensive Test Ban Treaty, which still awaits ratification from China, Iran, North Korea—and the United States. The backbone of the treaty is every nation’s ability to independently monitor the nuclear activity of the others. The noted seismologist Lynn R. Sykes, one of the central figures in the development of the science and technology used in monitoring, has dedicated his career to halting nuclear testing. In Silencing the Bomb, he tells the inside story behind scientists’ quest for disarmament. Called upon time and again to testify before Congress and to inform the public, Sykes and his colleagues were, for much of the Cold War, among the only people on earth able to say with certainty when and where a bomb was tested and how large it was. Methods of measuring earthquakes, researchers realized, could also detect underground nuclear explosions. When politicians on both sides of the Iron Curtain attempted to sidestep disarmament or test ban treaties, Sykes was able to deploy the nascent science of plate tectonics to reveal the truth. Seismologists’ discoveries helped bring about treaties limiting nuclear testing, but it was their activism that played a key role in the effort for peace. Full of intrigue, international politics, and hard science used for the global good, Silencing the Bomb is a timely and necessary chronicle of one scientist’s efforts to keep the clock from striking midnight.
