This book was released on 2012-12-06 with total page 867 pages. Available in PDF, EPUB and Kindle. Book excerpt: The subject of this NATO Advanced Study Institute was seismic monitoring under a nuclear test ban - an application of scienti fic knowledge and modern technology for a political purpose. The international political objective of a comprehensive nuclear test ban provided in turn the motivation for our technical and scientific discussions. In order to obtain a historical perspec tive on the progress of the work towards a comprehensive test-ban treaty (CTB), it is necessary to go back to 1958, when a confer ence of scientific experts in Geneva made the first steps toward an international seismic monitoring system. However, agreement on actual capabilities of a monitoring system for verifying compliance with such a treaty was not achieved, and thus the conference did not lead to immediate political results. After the Partial Test Ban Treaty of 1963, which banned nuclear explosions in the atmosphere, outer space and under the seas, renewed interest in the seismological verification of a CTB took place. A number of countries initiated large-scale research efforts toward detecting and identifying underground nuclear explosions, and it was in this context that the large aperture seismic arrays NORSAR and LASA were established. This type of development resulted in excellent seismic data in digital form and was thus of great irnprotance to the seismological com munity.

This book was released on 1967 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: The seismic effect of underground explosions in plastic argillaceous ground was investigated. In the first series of experiments, the dependence of ground motion on the amount of charge (q) and the distance (r) was analyzed; at this depth the strength and stability of the ground at the epicenter is not affected by the explosion. Records of the ground motion as a function of h show the presence of two types of oscillations. The same groups of waves, always observed independently of the amount of charge and h, made it possible to obtain travel-time curves for the first arrivals and characteristic phases. The second series of experiments conducted to obtain more precisely the dependence of ground motion on h. The ratio of amplitudes of surface waves did not remain constant. Formulas were derived for the ground-motion velocity of body and surface waves as a function of h, q, and r for reduced distance. Investigations were also conducted by placing three-component seismic receivers at depths of 5, 10, 15, 20, and 25 m in a shaft 1 m wide and 25 m deep. (Author).

Download or read book Earthquakes Induced by Underground Nuclear Explosions written by Rodolfo Console and published by . This book was released on 1995 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents different studies carried out on induced seismicity, both from experimental and theoretical viewpoints. Several examples of seismic activity induced by underground nuclear explosions, impoundment of artificial reservoirs, and mining activities are given and discussed. Another important subject which is covered is earthquakes induced by other large earthquakes. Further, tectonic stress release in the immediate vicinity of an underground nuclear explosion is treated. The release produces aftershocks of small magnitude, usually for several weeks, occurring a few kilometers within the shot point. This phenomenon is of importance in the context of monitoring a Comprehensive Test Ban Treaty.

Book excerpt: Seismic effects of Rainier, a 1.7-kt nuclear shot detonated 900 feet underground, were measured in terms of ground surface motion at ten strong-motion seismograph stations located 1200 to 45,000 feet from the source. In addition, records were borrowed from seven teleseismic stations located 100 to 300 miles from the source. Recorded accelerations attenuated from a maximum singlecomponent value of 2.6 g at 1280 feet to 0.009 g at 17,640 feet. Gutenberg-Richter magnitude of Rainier, calculated as for a natural earthquake from seven WoodAnderson seismograph records, was 4.6. Earthquakes of 4.6 magnitude are felt up to 60 miles from the epicenter, however, Rainier was felt by only a few observers at 21/2 miles. Seismologists at established teleseismic stations were able to pick out Rainier's elastic wave signature on seismograms at considerable distance. Very small amplitude waves from Rainier were found on the Coast and Geodetic Survey, College, Alaska, seismogram, 3600 km away, although attempts in the eastern United States at distances of 2000 to 3000 km, using conventional instruments, were not successful.

Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes work done after one year on project LL09-Sim-NDD-02 entitled 'Exploratory Research: Advanced Simulation of Low Yield Underground Nuclear Explosions To Improve Seismic Yield Estimation and Source Identification'. Work on this effort proceeded in two thrusts: (1) parametric studies of underground explosion generated motions with GEODYN; and (2) coupling of GEODYN to WPP. GEODYN is a code for modeling hydrodynamic (shock-wave) motions in a wide variety of materials, including earth materials. WPP is an anelastic finite difference code for modeling seismic motions. The sensitivity of seismic motions to emplacement conditions was investigated with a series of parametric studies of low-yield (0.2-4 kiloton) chemical high-explosive shots at a range of burial depths in four canonical geologic media (granite, limestone, tuff and alluvium). Results indicate that the material has a strong impact on the seismic motions consistent with previous reports. Motions computed with GEODYN in realistically complex material models are very consistent with reported motions from nuclear tests by Perret and Bass (1975). The amplitude, frequency content and cavity size resulting from explosions are all strongly sensitive to the material strength. Explosions in high-strength (granite) resulted in the highest amplitude, shortest duration pulse and smallest cavities, whereas explosions in low-strength material (alluvium) resulted in the lowest amplitudes, longest duration pulse and larger cavities. The corner frequencies of P-wave motions at take-off angles corresponding to propagation to teleseismic distances show corresponding behavior, with high-strength materials having the highest corner frequency and low-strength materials having low corner frequency. Gravity has an important effect on the cavity size and outgoing motions due work done against lithostatic stress. In fact without gravity the cavity radius and elastic motions are largely insensitive to depth of burial. We investigated the effects of depth of burial for a given yield and material model in the presence of gravity and found that the cavity radius is slightly smaller for deeper shots and the resulting motions have shorter duration and higher corner frequency compared to shallower shots. On the second thrust, progress has been made on one-way coupling of GEODYN to WPP. Early in the project we demonstrated this capability from one-dimensional (1D) GEODYN calculations. We have now completed the capability to pass motions computed in 2D or 3D with GEODYN to WPP and propagated (in 3D) to large distances.
