Download or read book Monitoring the Comprehensive Nuclear Test Ban Treaty Seismic Event Discrimination and Identification written by William R. Walter and published by Springer. This book was released on 2013-04-18 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: In September 1996, the United Nations General Assembly adopted the Comprehensive Nuclear-Test-Ban Treaty (CTBT), prohibiting nuclear explosions worldwide, in all environments. The treaty calls for a global verification system, including a network of 321 monitoring stations distributed around the globe, a data communications network, an international data center, and onsite inspections, to verify compliance. The problem of identifying small-magnitude banned nuclear tests and discriminating between such tests and the background of earthquakes and mining-related seismic events, is a challenging research problem. Because they emphasize CTBT verification research, the 12 papers in this special volume primarily addresses regional data recorded by a variety of arrays, broadband stations, and temporarily deployed stations. Nuclear explosions, earthquakes, mining-related explosions, mine collapses, single-charge and ripple-fired chemical explosions from Europe, Asia, North Africa, and North America are all studied. While the primary emphasis is on short-period, body-wave discriminants and associated source and path corrections, research that focuses on long-period data recorded at regional and teleseismic distances is also presented Hence, these papers demonstrate how event identification research in support of CTBT monitoring has expanded in recent years to include a wide variety of event types, data types, geographic regions and statistical techniques.

Available in PDF, EPUB and Kindle. Book excerpt: This book discusses three major physical phenomena for active source seismology, namely underwater explosions, underground nuclear explosions, and large-scale on-surface chemical explosions. In particular, contributors consider how to use the technologies and applications in active source seismology and seismo-acoustics, rather than the theoretical approach for the resolution of the forensic explosion seismology in the light of an application for defense sciences. The volume also presents seismological investigations of discrimination between earthquakes and man-made explosions.

Download or read book Monitoring the Comprehensive Nuclear Test Ban Treaty written by H.J. Patton and published by Springer Science & Business Media. This book was released on 2001-09-01 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Regional seismograms are dominated by the phases Pn, Pg, Sn, and Lg. More often Sn and Lg are used to infer the attenuation structure of the lithosphere. The seismic phase Sn is a high-frequency shear-wave (typically from 1 to 4 Hz and occasionally higher) that travels in the lithospheric mantle above the negative velocity gradient which usually marks the lithosphere-asthenosphere boundary. Sn has been reported out to distances of 35° (e. g. , MOLNAR and OLIVER, 1969; HUESTIS et aI. , 1973). Sn arrives as a high-frequency wave train lasting tens of seconds and up to 1 to 2 minutes. Sn velocities are typically 4. 7 km/s in stable continental and oceanic lithosphere (HUESTIS et al. , 1973) and as low as 4. 3 km/s (KADINSKY-CADE et al. , 1981) in more tectonically active regions. Lg is a complex short period guided wave consisting of high-frequency P and S energy which travels primarily in the earth's crust at frequencies typically between 0. 5 and 5 Hz. It has been modeled as higher-mode Love and Rayleigh waves as well as a sequence of multiply reflected post-critical S waves trapped in a crustal guide (BOUCHON, 1982; KENNETT, 1986; BOSTOCK and KENNETT, 1990). Lg has been observed not to propagate in oceanic or very thin continental crust (PRESS and EWING, 1952; SEARLE, 1975; ZHANG and LAY, 1995).

Book excerpt: "In The American Lab, former LLNL director Bruce Tarter captures the spirit of the Laboratory and its reflection of the broader world in which it thrived. He identifies the major themes that have characterized science and technology in the latter half of the twentieth century--the growth and decline of nuclear warheads, the unprecedented rise of supercomputing technology, laser systems, fusion, and mass spectrometry. He illuminates the Cold War dynamic from the participants' point of view--an unusual and valuable perspective on nuclear history. The story of the laboratory is a tale of three eras. Although the Lab took its research vision from European Edward Teller, its modus operandi came almost exclusively from namesake Ernest Lawrence and was subsequently invented in-house by its scientists and staff. During its first two decades the Lab's focus was almost entirely on nuclear weapons research and development, with a few other smaller enterprises that were technically related to the nuclear weapons activities. In the 1970s and 1980s, the Laboratory, along with many others in the Department of Energy complex, expanded into civilian pursuits that included energy, environment, biology, and basic science. A major program in laser science and technology became a cornerstone of this period. The third era was initiated by the end of the Cold War and saw the transformation of the traditional nuclear weapons activities into the stockpile stewardship program along with the rapid growth of projects that can be broadly characterized as homeland security. Tarter's history/memoir of the Lawrence Livermore National Laboratory, provides an insider's examination of nuclear science in the Cold War and the technological shift that occurred after the fall of the Berlin Wall."--Provided by publisher.
