Available in PDF, EPUB and Kindle. Book excerpt: Free-field recordings of underground nuclear explosions constitute a unique data set within the near-source region of seismic events ranging in magnitude from M3 to M6.5. The term ''free-field'' in this context refers to recordings from instruments emplaced in boreholes or tunnel walls such that the initial portions of the records ((almost equal to)0.1 to 1 second) do not contain effects resulting from reflections at the free surface. In addition to the free-field instruments deployed to record ground motions from selected underground nuclear explosions at the Nevada Test Site (NTS) and elsewhere, surface arrays were routinely deployed to record surface accelerations and velocities from underground nuclear tests conducted at NTS.

This book was released on 1996 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes available data on ground motions from underground nuclear explosions recorded on and near the Nevada Test Site, with emphasis on the ground motions recorded at stations on Yucca Mountain, the site of a potential high-level radioactive waste repository. Sandia National Laboratories, through the Weapons Test Seismic Investigations project, collected and analyzed ground motion data from NTS explosions over a 14-year period, from 1977 through 1990. By combining these data with available data from earlier, larger explosions, prediction equations for several ground motion parameters have been developed for the Test Site area for underground nuclear explosion sources. Also presented are available analyses of the relationship between surface and downhole motions and spectra and relevant crustal velocity structure information for Yucca Mountain derived from the explosion data. The data and associated analyses demonstrate that ground motions at Yucca Mountain from nuclear tests have been at levels lower than would be expected from moderate to large earthquakes in the region; thus nuclear explosions, while located relatively close, would not control seismic design criteria for the potential repository.

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.

This book was released on 1995 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: Certain difficulties arise when recording close-in around motion from underground nuclear explosions. Data quality can be compromised by a variety of factors, including electromagnetic pulse, noise spikes, direct current effect, and gauge clipping and gauge tilt. From March 1988 through September 1994, EG & G Energy Measurements repaired strong round-motion data (acceleration data) from underground nuclear tests for the Los Alamos National Laboratory using, an automated repair procedure. The automated repair determined and implemented the required repairs based on user input and a consistent set of criteria. A log was kept of each repair so that the repair procedure could be duplicated. This relaxed the requirement to save the repaired data. Developed for the VAX system, the procedure allowed the user to stack up a large number of repairs, plot the repaired data, and obtain hard copies. The plotted data could then be reviewed for a given test to determine the consistency of repair for a given underground test. This feature released the user to perform other tasks while the data were being repaired.

Available in PDF, EPUB and Kindle. Book excerpt: A review of ground shock data from recent large, near-surface high-explosive tests is made. Emphasis is on close-in motions in rock. Wave forms are shown for selected shots and locations. Comparisons are made among wave forms for similar test conditions in different geologic materials including soil, shale, granite, and sandstone. Variations in peak motion amplitudes at various depths and ranges are discussed for the different geologic materials. (Author).

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.
