Abstract:

A systematic analysis of buried explosions is performed for the purpose of determining how near-source effects influence seismic observations. Analytical Greens 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 explosionearth interactions while still allowing for important near-source variations. The theoreticalcomputational program is conducted in parallel with a review interpretative program of empirical data from a broad suite of geologic settings.
