Regional Seismic Wave Propagation
Abstract
Work has involved evaluation of method for using regional seismic waves, particularly Lg for yield determination. The Wake Island Hydrophone Array digital recording continues to provide high quality data. Polarization and array analyses have been made of Catskill Seismic Array and Regional Seismic Test Network data. For continental models, whole waveform synthetics demonstrate clearly the large dependence of the amplitude and spectral shape on the focal depth and the smaller dependence of these factors on focal mechanism. The broadband digital seismic station, SRNY has been in operation since 16 May 1984. Digital data are recorded magnetic cartridge tapes each capable of holding 67 Megabytes or 38 hours of data. Many programs have been developed for data handling and analysis. Keywords include: Pn and Sn, Yield determination, and Depth discrimination.
