Seismic Reflections at a Fault – A Model Study

E025 Seismic Reflections at a Fault – A Model Study J.R. van der Neut* (Delft University of Technology) M.K. Sen (University of Texas Institute for Geophysics) & K. Wapenaar (Delft University of Technology) SUMMARY A fault can be interpreted as a non-welded interface yielding a displacement discontinuity that can be described with a linear slip boundary condition. We use this BC to derive an exact algorithm for complexvalued reflection coefficients at a fault in a general anisotropic background. The fault is modeled as a layer of cracked material; its thickness being small compared to the seismic wavelength. We show how
