In this investigation, our first purpose is the regionalization of the Arctic region, Siberia and the Eurasian continental area using seismic surface waves. This regionalization will determine the structural properties of the upper few hundred kilometers of the earth, and the variation of these properties from one subregion to another in the area under investigation. Once the structural properties in the various regions have been obtained, our second purpose is to apply optimized computer techniques to the computation of accurate theoretical seismograms for any hypothetical type of source located anywhere within this continental area. These theoretical seismograms can be applied directly to the discrimination problem by comparing seismograms, computed for both earthquakes and underground explosions, with the actual recorder seismogram.
