Summary The analysis of surface waves from a large number of underground nuclear explosions reinforces the hypothesis of tectonic strain release. Such strain release is dependent on rock type and ambient stress levels. In harder media, such as granite, strain release is considerably greater than in soft media such as loose alluvium and by:   Tectonic Strain Release by Underground Nuclear Explosions and its Effect on Seismic DiscriminationCited by: 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. Tectonic strain release by underground nuclear explosions Toksoz, M. N. Abstract. Static and dynamic methods are developed to study the elastic field produced by earthquake faulting. An earthquake is considered as the slip on a planar fault due to frictional instability. The dynamics of a circular fault model is considered as a circular rupture Cited by: 3.

In this paper, an alternative decomposition scheme is proposed to deal with the moment tensor of underground nuclear explosions, which might benefit the approach to study the tectonic strain release induced by underground nuclear by: 1. Determination of source parameters by amplitude equilization of seismic surface waves, 2, Release of tectonic strain by underground nuclear explosions and mechanisms of earthquakes. J. : S. K. Guha, S. K. Guha. A number of seismic source models for underground nuclear explosions have been developed over the past 2 decades. These models include the spherically symmetric compressional source model, the wave conversion source model, the tectonic strain release source model, the spall slapdown source model, and the near-regional source by:   The Theory of Stress Wave Radiation from Explosions in Prestressed Media Charles B.

Gianni Petrangeli, in Nuclear Safety, The possible effects of an underground nuclear explosion. Underground nuclear explosions are usually performed at a depth of hundreds of metres in order to avoid any consequences, radioactivity releases in particular, on the surface.. The known effects of an underground explosion are the melting of rocks near the bomb and their fracturing for. Strain-step data, termed “zero-frequency seismology” (Press, ), seemed to give a win-dow into the interaction of tectonic processes and sudden strain release; this interaction was of interest in the problem of identifying nuclear explosions because any tectonic strain. Release of tectonic strain by underground nuclear explosions and mechanisms of earthquakes. Abstract. The radiation patterns of Love and Rayleigh waves from three nuclear explosions (Hardhat, Haymaker, and Shoal) are studied to determine the nature of the asymmetry of radiation and the mechanism of Love wave by: Fault dislocation driven by the hoop stress associated with the Pwave from an underground explosion is proposed as a mechanism for tectonic stress release. The mechanism is examined in two-dimensional numerical simulations. Determined initial value problems can be posed, from which plots of near-field motion are obtained.
