Identification of Earthquakes and Underground Explosions
Abstract
Research during the reporting period was accomplished in four categories: (a) Analysis of Rayleigh wave dispersion for polar paths; (b) development of improved array processing techniques; (c) determination of bias in network computations of body wave magnitudes; and (d) investigation of the effect on the Rayleigh spectrum of lateral heterogeneity in earthquake source regions. Because of the uniformity of group velocity dispersion within the polar wave guide and the broad-band nature of the Rayleigh waves, 'matched' or chirp- filter techniques were found to be particularly effective on data recorded at McKinney, TX, site.
