Obtaining Unique, Comprehensive Deep Seismic Sounding Data Sets for CTBT Monitoring and Broad Seismological Studies
Abstract
In cooperation with the Center for Geophysical and Geoecological Studies (GEON, Moscow, Russia), the University of Wyoming and now also with the University of Saskatchewan digitized, edited, transferred into standard digital formats, and delivered to public domain seismic records from 12 major Deep Seismic Sounding (DSS) projects acquired in 1970-1980's in the former Soviet Union. The data include 3-component records from 22 Peaceful Nuclear Explosions (PNEs) and over 500 chemical explosions recorded by a grid of linear, reversed seismic profiles covering a large part of Northern Eurasia. Digital copies of all records were delivered to AFRL and to the Incorporated Research Institutions for Seismology Data Center for unrestricted distribution to researchers. The availability of the DSS PNE datasets resulting from this project, combined with the recent results arising from them (velocity, reflectivity, Receiver Functions, mantle attenuation, Lg Q, P- and Lg coda Q, scattering, phase amplitude ratios, empirical first-arrival travel times) makes the area of PNE profiling one of the best-constrained seismically at short periods, both for structural studies and for nuclear test monitoring.
