Abstract
Three-component three-dimensional seismic data is acquired by locating a plurality of receivers off the seisimic shot line of a seismic source. The angle between the seismic shot line and a line extending between the seismic source and each receiver is used to normalize the signals generated by the two shear wave detectors in each receiver by mathematically rotating the orientation of the receiver and the orientation of the seismic source to produce horizontal shear wave signals and vertical shear wave signals generally equivalent to those that would have been produced if each receiver and seismic source were aligned along a seismic shot line.
