Coupling Near Source Phenomena into Surface Wave Generation

David G. Harkrider

Theoretical explosion mechanisms for an all azimuth reversal of Rayleigh waves are presented. Linear code methods for modeling nonlinear source region phenomena and techniques for coupling near source phenomena into surface wave generation, such as vertical separation of source radiation, mixed path approximations, and the elastodynamic representation theorem are reviewed. Qualitative and quantitative results obtained using these algorithms, in particular source medium scaling, are discussed.
