Tianshan Tectonic Belt is a major seismic activity belt in the western part of the Chinese mainland. A recent study revealed the anisotropic zoning in the upper crust of the Tianshan tectonic belt, The polarization directions of the fast waves in most of the study area are consistent with the local tectonic stress fields, the time delays share an increasing trend from east to west in the NorthTianshan and South Tianshan Mountain ranges.
