Numerical modeling of elastic wave scattering by near-surface heterogeneities
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2013)
A perturbation method for elastic waves and numerical forward modeling are used to calculate the effects of seismic wave scattering from arbitrary shape shallow subsurface heterogeneities. Wave propagation is simulated ...
Finite Difference Elastic Wave Modeling Including Surface Topography
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2011)
Surface topography and the weathered zone (i.e., heterogeneity near the earth’s surface) have great effects on elastic wave propagation. Both surface waves and body waves are contaminated by scattering and conversion by ...
