Underground 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 PARAMETERS OF EARTHQUAKES, AND DISCRIMINATION BETWEEN EARTHQUAKES AND NUCLEAR EXPLOSIONS BY JOH~ B. DAvIEs A~D
The first part of this study describes a technique by which the source parameters of an earthquake can be obtained from the spectrum of compressional waves. The source parameters defined are fault length, fracture velocity, and fault plane attitude. Two large, deep earthquakes are examined using this technique. The source parameters determined compare favorably with those obtained previously us...
متن کاملA Comparative Study of the Elastic Wave Radiation from Earthquakes and Underground Explosions*
A detailed analysis of the surface wave radiation from two underground explosions (BILBY and SHOAL) and an earthquake near Fallon, Nevada, whose epicentre is only 60 km from SHOAL, indicates that: (1) at long periods the surface wave radiation from the earthquake can be explained by a pure quadrupole (double couple) source, but at higher frequencies the radiation pattern contains asymmetries wh...
متن کاملANALYSIS OF HIGH-FREQUENCY Pg/Lg RATIOS FROM NTS EXPLOSIONS AND WESTERN U.S. EARTHQUAKES
The high-frequency P g /L g discriminant is studied between frequencies of 0.5 and 10 Hz using 294 NTS explosions and 114 western U.S. earthquakes recorded at four broad band seismic stations operated by Lawrence Livermore National Laboratory. The stations are located at distances of about 200 to 400 km from the Nevada Test Site (NTS). Event magnitudes ranged from about 2.5 to 6.5 and propagati...
