Velocity is a fundamental property of rocks that depends on density and elastic moduli. It varies laterally as well as vertically due to the physical-geologic variations of rocks. Velocities are ...

Seismic velocity changes provide a window into the dynamic behaviour of the Earth’s crust and constitute a vital parameter in earthquake monitoring. Recent advances have refined methods for detecting ...

Curved-ray prestack Kirchhoff time migration is rapidly replacing other seismic time migration methods for focusing seismic images of subsurface structures. For most geologic environments, curved-ray ...
