Abstract

A method of determining the polarisation directions of the fast and slow shear waves arising from shear wave splitting due to anisotropy, said directions defining a natural coordinate system, the method comprising the steps of: a) recording at least two components of each shear wave, in a recording coordinate system, b) calculating the value of υ, being the angle of rotation between the natural coordinate system and the recording coordinate system, for which the Lp norm of the rotated traces is minimised if p is less than 2, or maximised if p is greater than 2.
