If the vertically-aligned parallel fractures in the subsurface are filled with fluid, or weakly cemented, the P-wave velocity across the fractures will be slower than that parallel to the fractures. These differences give rise to a velocity variation with azimuth. Because impedance is the product of density and velocity, such fractures also give rise to amplitude variation with offset.--><!-- NOHTML: --><!--ASDF-1/1/1999 12:00:00 AM-->
