One purpose of this project was to determine the regional variations of the crust and upper mantle in the regions under investigation using the properties of surface wave dispersion in the Arctic region and the Eurasian continental area. The regions of high seismicity within and around the region, plus the dense set of WWSSN stations located around the perimeter of the region, gave assurance that we could acquire sufficient single-station phase velocity data for the application of regionalization procedures. A second purpose was to develop computational techniques for calculating complete, accurate theoretical seismograms for both earthquake and explosion sources within the area under investigation, and which could be compared with those recorded at the WWSSN and HGLP stations at the edge of this region.
