Available in PDF, EPUB and Kindle. Book excerpt: Quantification of physical processes near an explosion that contribute to the radiated seismic wavefield was the goal of this work. Characterization of both nuclear and chemical explosions using near-source observations was conducted. This report is divided into six sections. The first is a review research in nuclear seismology, Nuclear Explosion Seismology: Verification, Source Theory, Wave Propagation and Politics. The second contribution reviews the types of free-field and free surface data recorded from nuclear explosions, Free-Field and Free-Surface Ground Motions from Nuclear Explosions, Their Spatial Variation and the Constraints of Physical Source Mechanisms. The third paper is a numerical study designed to investigate the scatter observed in near-source observations, Variability of Near-Source Waveforms from Contained Explosions - Pahute Mesa, A Case Example. The fourth section describes the source characterization of a moderate size explosion in Yucca Flats. Both the isotropic and deviatoric source contributions are characterized, Isotropic and Deviatoric Characterization of Coalora Nuclear Explosion in Yucca Flats. The fifth paper reports on the characterization of chemical explosions in a cylindrical geometry, Near-Source Characterization of the Seismic Wavefield Radiated from Quarry Blasts. The final contribution, Physical Models of Spall Zone Ground Motions and the Determination of Spatial Decay Rates, is presented only in abstract form. This work was cooperative with the Source Region Program at Los Alamos National Laboratory and has been published under LAUR-92-451.
