Determination of seismic source parameters from long-period surface wave data. Technical report
Technical Report
·
OSTI ID:6952815
Far-field Rayleigh and Love waves observed on a long-period seismic network were studied to characterize presumed underground nuclear explosions. These occurred at the United States Nevada Test Site (NTS), the Russian eastern Kazakh (EKZ) region, and at the site of presumed peaceful nuclear explosions (PNE) in the north Caspian Sea region. The observation stations available for this study included Alaskan Long Period Array (ALPA), Large Aperture Seismic Array (LASA), Norwegian Seismic Array (NCRSAR), the Very Long Period Experiment (VLPE) stations, the Seismic Research Observatories (SRO), and the Special Data Collection System (SDCS) stations. The purpose of this study was to determine the seismic source parameters from long-period surface wave data and to investigate the influence of geological and near-source propagation effects on the frequency content of the surface wave signals.
