GPS results show the movement velocity of surface, which can testify the complicated stress field, just like seismic anisotropy in crust can do;

To explore the complex oil and gas reservoir, multi-component seismic technique, based on the theory of seismic anisotropy, has been applied a lot to some extend.

Seismic activity and seismic relocation can show the regional structure information, which just correspond to the structure information shown by seismic anisotropy in crust.
