Delayed signatures of underground nuclear explosions.
Radionuclide signals from underground nuclear explosions (UNEs) are strongly influenced by the surrounding hydrogeologic regime. One effect of containment is delay of detonation-produced radioxenon reaching the surface as well as lengthening of its period of detectability compared to uncontained explosions. Using a field-scale tracer experiment, we evaluate important transport properties of a f...
متن کاملSustainable development in Urban Underground Space
During a very long period of time, civil engineers have been the only ones to be designated as the experts for underground space, while the planners and architects were the ones of the development at the surface. Cities worldwide tend to overlook an invaluable asset that lies beneath their surfaces. Most cities and urban regions are unaware of the benefits underground space use has to offer, bo...
متن کاملAnalysis of Regional Seismic Data for Underground Explosions
In recent years, numerous regional seismic event discrimination studies have shown that the high-frequency (usually greater than 3–4 Hz), P/S spectral amplitude ratios of regional P (Pg or Pn) and S (Sg, Sn or Lg) waves observed at distance range from few kilometers up to about 2,000 kilometers, provide an efficient method to classify regional earthquakes, quarry blasts and underground nuclear ...
متن کاملUnderground nuclear explosions and the control of earthquakes.
Underground nuclear explosions trigger significant earthquake activity for at least 32 hours afterward and to distances up to at least 860 kilometers. The proposed Amchitka test may be used to study the feasibility of employing high-yield underground nuclear explosions to release stresses accumulating in the lithosphere. Periodical explosions along active fault zones may be used to prevent disa...
متن کاملObservations ofTeleseismic P Wave Coda for Underground Explosions
-The early P wave coda (5-15 sec after the first arrival) of underground explosions at the Nevada Test Site is studied in the time domain using 2082 teleseismic short-period recordings, with the intent of identifying near-source contributions to the signals in the frequency range 0.2-2.0 Hz. Smaller magnitude events tend to have relatively high coda levels in the 0.4-0.8 Hz frequency band for b...
