Near-Source Phenomena and Their Manifestations on Signatures of More Distant Radiation of Seismic Energy

Abstract

A systematic analysis of buried explosions is performed for the purpose of determining how near-source effects influence seismic observations. Analytical Green's function methods are developed and used to efficiently and accurately extend representations of seismic radiaton to the far-field domain of interest. Representations of nonlinear processes and near-source inhomogeneities are provided that simplify the complexities of near-source explosion/earth interactions while still allowing for important near-source variations. The theoretical/computational program is conducted in parallel with a review/ interpretative program of empirical data from a broad suite of geologic settings.
