Seismic Coupling from a Nuclear Explosion:The Dependence of the Reduced Displacement Potential on the Nonlinear Behavior of the Near Source Rock Environment.

摘要

The objective of the research presented in this report is to determine the dependence of teleseismic magnitudes on the nonlinear behavior of the near source rock environment. Such information enables one to express uncertainties in explosive yield estimates in terms of uncertainties in the material properties and provides insight concerning the requirements for collection of geophysical data at a specific test site. A series of spherically symmetric calculations have been performed in which the properties of the near source material were varied systematically. Output from these calculations enables one to determine the relative teleseismic coupling efficiency of a given near source material. Also,since seismic magnitudes are directly related to explosive yield,this parameter study permits an assessment of uncertainties in the estimated yield in terms of uncertainties of the material properties of the test site.
