Seismic Wave Propagation and Earthquake Characteristics in Asia

Abstract

The great influence of the way in which inelastic attenuation is modelled on the results obtained for seismic source parameters from wave spectra has led to an investigation of better ways of arriving at the required corrections to raw seismogram spectra. A procedure, based on a relaxation model of attenuation, for using a frequency-dependent Q in the program for computing source spectra has been developed. The resulting effective Q's tie together apparently disparate results obtained by others for short-and long-period attenuation. Moments and corner frequencies for 12 central Asian earthquakes in four selected seismic zones in western China and Siberia have been determined from P- and S-body wave spectra.
