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 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 کاملSource Models and Yield-scaling Relations for Underground Nuclear Explosions at Amchitka Island by Thorne Lay*,
Source models are determined for the three underground nuclear explosions at the Amchitka test site using seismic observations in the period range 0.5 to 20.0 sec. Empirical yield-scaling relations are inferred from the source models and compared with the predictions of the Haskell, Mueller-Murphy, and finite difference numerical models. Several recent studies of high-frequency, near-field sign...
متن کاملTHE STABILITY OF RMS Lg MEASUREMENTS AND THEIR POTENTIAL FOR ACCURATE ESTIMATION OF THE YIELDS OF SOVIET UNDERGROUND NUCLEAR EXPLOSIONS
Data on underground nuclear explosions have recently become available from modern digital seismic stations installed within the Soviet Union and China. Observations of root mean square (rms) Lg-wave signals for Soviet underground nuclear explosions at the Shagan River Test Site in East Kazakhstan show that the relative amplitudes of the rms signals at stations in Norway, the USSR, and China are...
متن کاملCalculation of the real part of the nuclear amplitude at high s and small t from the Coulomb amplitude
Calculation of the real part of the nuclear amplitude at high s and small t from the Coulomb amplitude A new method for the determination of the real part of the elastic scattering amplitude is examined for high energy proton-proton at small momentum transfer. This method allows us to decrease the number of model assumptions, to obtain the real part in a narrow region of momentum transfer and t...
