Available in PDF, EPUB and Kindle. Book excerpt: Seismic detection of small, evasively tested underground nuclear explosions remain as a major challenge to effective verification of any eventual CTBT. Most seismic detection research reported to date has focused on analyses of regional seismic signals recorded from explosions at the few known nuclear weapons test sites and, consequently, represent only limited ranges of the source and propagation path conditions of potential monitoring interest. In this study, we analyze regional seismic data recorded at the Borovoye station in Central Asia from a selected group of Soviet PNE tests which sample wider ranges of the source and propagation path variables of interest. The results of these analyses have indicated that it will in general be difficult to seismically detect low-yield, cavity decoupled nuclear explosions, even with high quality stations at regional distance of 100 or less, and that additional research will be required to optimize the seismic networks and signal processing systems needed to monitor such clandestine tests.

This book was released on 1995 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: Until the late 80's information on Soviet underground nuclear explosions, let alone seismic recording on Soviet soil, were not generally available to the seismological community. The dramatic changes since then have resulted in access to a wide variety of seismic data from Soviet explosions. In this report we present a data set, unique to the field of seismic verification. The data includes a large number of waveforms from in-country seismological station Borovoye for the Soviet peaceful nuclear explosions with announced yields and origin times, some with physical and mechanical conditions at the test site. The waveforms were recorded by digital station of different types. In this report we have summarized and reviewed information on 122 explosions, and 55 waveforms in this data set, which contains recordings obtained in the course of more than 15 years. As the characteristics of recording instruments were changing during this period of time available information on instrument calibrations is also described and reviewed. We also have attempted to describe the observed peculiarities of P-wave by using a simple source function and magnitude correction which take in attention such parameters as the velocity of longitudinal wave, density, moisture, gas content and depth of explosion. More detail analysis was conducted for the explosions conducted in salt as there is representative sample and they were observed on local distances.

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.

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 excerpt: Originally published in 1985, the level of anxiety and suspicion between the USA and the USSR had rarely been higher. Many advocates of arms control believed that effective verification would reduce tensions and lessen the risk of war. This book analyses the two main issues of verification. One is technological: what are the present capabilities of various verification techniques and what is their potential? The devices and methods currently employed by the two major nuclear powers and by international organizations to monitor the compliance of states with arms control or disarmament treaties are examined. The second issue is political: how do US and Soviet approaches compare, what are the roles of domestic and bureaucratic politics, and on what criteria can a workable standard of adequacy be based? In short, how much is enough? Although the study concludes that a number of significant arms control measures can already be adequately verified, modern weapons are becoming more mobile and it is becoming easier to conceal them. There is a danger that the ability to hide weapons will outstrip the ability to find them. Verification cannot promise to detect all violations; a workable standard of adequacy in verification must derive from the ability to detect militarily significant violations.

Book excerpt: Project 1.7 of Operation TEAPOT was concerned with the measurement of surface and subsurface effects of an underground explosion of a 1.2-kt nuclear burst (Shot 7). The measurements included free-field earth and airblast effects, as well as loading on underground structural devices. This report deals with the presentation and analysis of the free-field data only; the structural data have been transmitted to the appropriate agencies for their analysis. From the 76 channels installed on TEAPOT Shot 7, 75 usable records were obtained. The free-field quantities measured include air-blast pressure, earth acceleration, earth stress and strain, and permanent earth displacement. The results are discussed by phenomenon and, in each case, the TEAPOT data are compared with pretest predictions. Also, where data are available, comparisons are made with previous underground nuclear test results. Some aspects of seismology and soil mechanics as applied to underground explosion phenomena are presented and, finally, the most pertinent high explosives results from subsequent tests conducted at the TEAPOT location are summarized.
