Fast orientation at most of the stations on the Tien Shan range is ENE-WSW, parallel to the strike of the Tien Shan.

Anisotropy with NNE-SSW fast axes is observed within adjacent basins, around the Issyk Kul and near the northwestern Tarim, where the lithosphere is presumably strong, less deformed. The NNE-SSW orientation, which coincides with the surface velocity of the central Tien Shan, can be best explained by shear between the lithosphere and asthenosphere on a regional scale rather than small-scale convection as proposed in previous studies. The dextral Talasso-Fergana fault seems to have little effect on anisotropy at its nearby stations, suggesting this fault is probably confined to the shallow part of the lithosphere. %@ 0094-8276
