Abstract
A method for correction of seismic data for taking into account azimuthal anisotropy in the subsurface is described. The data is corrected using an azimuthally anisotropic normal moveout equation, thereby yielding better signal to noise ratio as well as providing valuable information as to the degree and direction of azimuthal anisotropy in the subsurface.
