Reflector rotation

Reflector rotation attribute quantifies the rotation of fault blocks across discontinuities such as wrench faults.  It is a measure of the change in reflector normal about a more or less vertical axis.

 

Time slice at 1.190 s from the coherence volume and vertical slices through seismic amplitude co-rendered with vector rotation.  Red indicates down to the right across the fault, while blue indicates up to the right across the fault.
