SUMMARY A tomographic inversion method is presented for the determination of 3-D velocity and interface structure from a wide range of body-wave seismic traveltime data types. It is applicable to… (More)
The crustal velocity structure and the Moho depth of the Proterozoic Torngat Orogen, NE Canada, is determined by active seismic tomography using travel times of crustal turning rays and Moho… (More)
We present a new method for correcting the amplitudes of arrivals in an acoustic finite-difference simulation for elastic effects. In this method, we selectively compute an estimate of the error… (More)
Acoustic finite-difference modelling is playing an increasingly important role in seismic imaging (e.g. in reverse time migration) but the additional cost of elastic finite-difference modelling… (More)
SUMMARY When velocity models are built for Kirchhoff pre-stack depth migration, complex, high-contrast features such as salt boundaries are usually represented explicitly during the model-building… (More)
We develop a ray-based prestack depth migration algorithm for general anisotropic media. We demonstrate the capability of our algorithm for orthorhombic anisotropy using synthetic and real data… (More)
