Three-dimensional first arrival traveltimes and amplitudes via eikonal and transport finite difference solvers
First arrival traveltimes and associated amplitudes are essential components in Kirchhoff migration and modeling. Traditionally they have been determined by ray tracing. However ray tracing does not give traveltimes on a ...
Combining deterministic and stochastic velocity fields in the analysis of deep crustal seismic data
Standard crustal seismic modeling obtains deterministic velocity models which ignore the effects of wavelength-scale heterogeneity, known to exist within the Earth's crust. Stochastic velocity models are a means to include ...
Global analysis of linearized inversion for the acoustic wave equation
To predict the location of natural resources and reduce the cost of exploration, geophysicists rely on various techniques to map the internal structure of the earth. One common mapping method probes the earth's interior ...
