| Abstract: | Using GPS measurements in the Northern Tienshan Mountains from 1998 to 2008, we obtain the present day crustal movement velocity field for more than 30 sites, at the same time, estimate active rates on the major faults in the studied region. The GPS velocity results show that there is non uniformity for N S direction crustal shortening of northern Tianshan area and it shows the correlation between the differences of the absorption rate and frequency of the earthquake occurring. The active faults movement characters derived from the GPS measurement results are consistent with the geological results, but there are differences in the value. |
