- Abstract:
- Based on GNSS data，the strain rate tensor in Xinjiang and its adjacent areas is calculated by using the spherical least squares collocation method.The relationship between the strain rate and the distribution of M ≥6.0 earthquakes in the study area during 1900-2022 is statistically analyzed.Then the indicative significance of GNSS strain rate characteristics for strongearthquake locations is studied.The major faults deformation characteristics in the study area are inversed with the threedimensional elastic block model.And on the basis of the focal mechanism solutions，the relationship between the faults deformation characteristics and the types of strong earthquakes in the study area is analyzed.The results show that the second strain rate value is high in the west TianshanPamir region and in the adjacent areas of the Altyn fault zone，with the highest value near the Pamir structural juncture.The maximum shear strain rate direction in the Southern Tianshan Mountains and Pamir region is mainly NENEE，reflecting the characteristic of the area dominated by dipslip deformation.The M ≥6.0 earthquakes are mainly distributed in the high strain rate areas and their margins，especially in the eastern region of the Pamir tectonic junction.The fault movement in the area has obvious classification features.The faults in the study area are featured as compression movement on the whole.The NEtrending fault zone is mainly leftlateral，strikeslip，and the NWtrending fault is mainly rightlateral，strikeslip.Strong earthquakes concentrate in the western section of the South Tianshan Mountains and the eastern part of the Pamir syntax，where the NEtrending Keping fault zone，the NEtrending Maidan fault zone，the NEtrending Narati fault zone，the NWtrending Kiziletao fault zone，the NEtrending TalasFergana fault zone converge.In the area the focal mechanism of strong earthquakes is consistent with the faults movement pattern.
