Application of Advanced Methods for Identification and Detection of Nuclear Explosions from the Asian Continent
Abstract
The report presents the results of a continuing effort to obtain an optimum multi-discriminant/detection procedure for earthquakes and explosions occurring within the Asian Continent. Significant improvement of theoretical predictions of teleseismic ground motion from explosions was realized using a deterministic computer model which merges nonlinear shock code calculations with far-field stress wave propagation through a realistic earth structure. The addition to the seismic codes of the Thomson-Haskell matrix formulation and a split earth structure capability provides for the inclusion of more realistic earth structure models in the near source and receiver regions and for the intervening path in the upper mantle. The resulting theoretical seismograms show a striking similarity to observations and indicate that a successful matched filter for event detection and discrimination, based on a substantial portion of an event signal, can be constructed.
